USB flash installation medium (Magyar)
Archiso
is a highly-customizable tool for building Arch Linux live CD/USB ISO images, netboot artifacts and bootstrap tarballs. The
official images
are built with archiso and include the
following packages
. It can be used as the basis for rescue systems, linux installers or other systems. This wiki article explains how to install archiso, and how to configure it to control aspects of the resulting ISO image such as included packages and files. Technical requirements and build steps can be found in the
official project documentation
. Archiso is implemented with a number of bash scripts. The core component of archiso is the
mkarchiso
command. Its options are documented in
mkarchiso -h
and not covered here.
Telepítés
Install
the
archiso
package.
Prepare a custom profile
Megjegyzés
You can read about profiles in-depth in the archiso project's
README.profile.rst
.
Archiso comes with two profiles,
releng
and
baseline
.
releng
is used to create the official monthly installation ISO. It can be used as a starting point for creating a customized ISO image.
baseline
is a minimal configuration, that includes only the bare minimum packages required to boot the live environment from the medium.
To build an unmodified version of the profiles, skip to
#Build the ISO
. Otherwise, if you wish to adapt or customize one of archiso's shipped profiles, copy it from
/usr/share/archiso/configs/
profile-name
/
to a writable directory with a name of your choice. For example:
$ cp -r /usr/share/archiso/configs/releng/ archlive
Proceed to the following sections to customize and build the custom profile.
Profile structure
An archiso profile contains configuration that defines the resulting ISO image. The profile structure is documented in
/usr/share/doc/archiso/README.profile.rst
[1]
.
Selecting packages
Edit
packages.x86_64
to select which packages are to be installed on the live system image, listing packages line by line.
Custom local repository
To add packages not located in standard Arch repositories (e.g. packages from the
AUR
or customized with the
ABS
), set up a
custom local repository
and add your custom packages to it. Then add your repository to
pacman.conf
as follows:
archlive
/pacman.conf
...
[
customrepo
]
SigLevel = Optional TrustAll
Server = file://
/path/to/customrepo
...
Megjegyzés
The ordering within
pacman.conf
matters. To give top priority to your custom repository, place it above the other repository entries.
This
pacman.conf
is only used for building the image. It will not be used in the live environment. To do this, see
#Adding repositories to the image
.
Ensure that the repository is located in a directory accessible by the chrooted
mkarchiso
process, such as
/tmp
, to ensure the repository is read correctly during the image building process.
mkarchiso will look for a repo called
custom
, so when you create it run:
$ repo-add /path/to/custom.db.tar.zst /path/to/package-1.0-1-x86_64.pkg.tar.zst
Packages from multilib
To install packages from the
multilib
repository, simply uncomment that repository in
pacman.conf
.
Adding files to image
The airootfs directory is used as the starting point for the
root directory
(
/
) of the live system on the image. All its contents will be copied over to the working directory before packages are installed.
Place any custom files and/or directories in the desired location under
airootfs/
. For example, if you have custom nftables rules on your current system you want to be used on your live image, copy them over as such:
$ cp /etc/nftables.conf
archlive
/airootfs/etc/
Similarly, some care is required for special configuration files that reside somewhere down the hierarchy. Missing parts of the directory structure can be simply created with
mkdir(1)
.
Tipp
To add a file to the install user's home directory, place it in
archlive
/airootfs/root/
. To add a file to all other users home directories, place it in
archlive
/airootfs/etc/skel/
.
Megjegyzés
Custom files that conflict with those provided by packages will be overwritten unless a package specifies them as
backup files
.
By default,
permissions
will be
644
for files and
755
for directories. All of them will be owned by the root user. To set different permissions or ownership for specific files and/or folders, use the
file_permissions
associative array in
profiledef.sh
. See
README.profile.rst
for details.
Adding repositories to the image
To add a repository that can be used in the live environment, create a
suitably modified
pacman.conf
and place it in
archlive
/airootfs/etc/
.
If the repository also uses a key, place the key in
archlive
/airootfs/usr/share/pacman/keyrings/
. The key file name must end with
.gpg
. Additionally, the key must be trusted. This can be accomplished by creating a GnuPG exported trust file in the same directory. The file name must end with
-trusted
. The first field is the key fingerprint, and the second is the trust. You can reference
/usr/share/pacman/keyrings/archlinux-trusted
for an example.

$ pacman-key --add archzfs.gpg
# pacman-key --lsign-key DDF7DB817396A49B2A2723F7403BD972F75D9D76
Kernel
Although both archiso's included profiles only have
linux
, ISOs can be made to include other or even multiple
kernels
.
First, edit
packages.x86_64
to include kernel package names that you want. When
mkarchiso
runs, it will include all
work_dir
/airootfs/boot/vmlinuz-*
and
work_dir
/boot/initramfs-*.img
files in the ISO (and additionally in the FAT image used for UEFI booting).
mkinitcpio
presets by default will build fallback initramfs images. For an ISO, the main initramfs image would not typically include the
autodetect
hook, thus making an additional fallback image unnecessary. To prevent the creation of an fallback initramfs image, so that it does not take up space or slow down the build process, place a custom preset in
archlive
/airootfs/etc/mkinitcpio.d/
pkgbase
.preset
. For example, for
linux-lts
:
archlive
/airootfs/etc/mkinitcpio.d/linux-lts.preset
PRESETS=('archiso')

ALL_kver='/boot/vmlinuz-linux-lts'
archiso_config='/etc/mkinitcpio.conf.d/archiso.conf'

archiso_image="/boot/initramfs-linux-lts.img"
Finally create
boot loader configuration
to allow booting the kernel(s).
Boot loader
Archiso supports
syslinux
for BIOS booting and
GRUB
or
systemd-boot
for UEFI booting. Refer to the articles of the
boot loaders
for information on their configuration syntax.
Tipp
The
releng
profile by default builds into an ISO that supports both BIOS and UEFI booting when burned to an optical disc using El Torito, or when written to a hard disk (or USB flash drive, or similar) using
Isohybrid
.
Due to the modular nature of isolinux, you are able to use lots of addons since all
.c32
files are copied and available to you. Take a look at the
official syslinux site
and the
archiso git repo
. Using said addons, it is possible to make visually attractive and complex menus. See
[2]
.
mkarchiso expects that GRUB configuration is in the
grub
directory,
systemd-boot
configuration is in the
efiboot
directory and
syslinux
configuration in the
syslinux
directory.
UEFI Secure Boot
If you want to make your archiso bootable on a UEFI Secure Boot enabled environment, you must use a signed
boot loader
. You can follow the instructions on
Secure Boot#Booting an installation medium
.
systemd units
To
enable
systemd services/sockets/timers for the live environment, you need to manually create the symbolic links just as
systemctl enable
does it.
For example, to enable
gpm.service
, which contains
WantedBy=multi-user.target
, run:
$ mkdir -p
archlive
/airootfs/etc/systemd/system/multi-user.target.wants
$ ln -s /usr/lib/systemd/system/gpm.service
archlive
/airootfs/etc/systemd/system/multi-user.target.wants/
The required symlinks can be found out by reading the systemd unit, or if you have the service installed, by
enabling
it and observing the systemctl output.
Login manager
Starting X at boot is done by enabling your login manager's
systemd
service. If you do not know which
.service
to enable, you can easily find out in case you are using the same program on the system you build your ISO on. Just use:
$ ls -l /etc/systemd/system/display-manager.service
Now create the same symlink in
archlive
/airootfs/etc/systemd/system/
. For LXDM:
$ ln -s /usr/lib/systemd/system/lxdm.service
archlive
/airootfs/etc/systemd/system/display-manager.service
This will enable LXDM at system start on your live system.
Changing automatic login
The configuration for getty's automatic login is located under
airootfs/etc/systemd/system/getty@tty1.service.d/autologin.conf
.
You can modify this file to change the auto login user:
[Service]
ExecStart=
ExecStart=-/sbin/agetty --noreset --noclear --autologin
username
- ${TERM}
Or remove
autologin.conf
altogether to disable auto login.
If you are using the serial console, create
airootfs/etc/systemd/system/serial-getty@ttyS0.service.d/autologin.conf
with the following content instead:
[Service]
ExecStart=
ExecStart=-/sbin/agetty --noreset --noclear --autologin root --keep-baud 115200,57600,38400,9600 - ${TERM}
Users and passwords
To create a
user
which will be available in the live environment, you must manually edit
archlive
/airootfs/etc/passwd
,
archlive
/airootfs/etc/shadow
,
archlive
/airootfs/etc/group
and
archlive
/airootfs/etc/gshadow
.
Megjegyzés
If these files exist, they must contain the root user and group.
For example, to add a user
archie
. Add them to
archlive
/airootfs/etc/passwd
following the
passwd(5)
syntax:
archlive
/airootfs/etc/passwd
root:x:0:0:root:/root:/usr/bin/zsh
archie:x:1000:1000::/home/archie:/usr/bin/zsh
Megjegyzés
The
passwd
file must end with a newline.
Add the user to
archlive
/airootfs/etc/shadow
following the syntax of
shadow(5)
. If you want to define a password for the user, generate a password hash with
openssl passwd -6
and add it to the file. For example:
archlive
/airootfs/etc/shadow
root::14871::::::
archie:$6$randomsalt$cij4/pJREFQV/NgAgh9YyBIoCRRNq2jp5l8lbnE5aLggJnzIRmNVlogAg8N6hEEecLwXHtMQIl2NX2HlDqhCU1:14871::::::
Otherwise, you may keep the password field empty, meaning that the user can log in with no password.
Add the user's group and the groups which they will part of to
archlive
/airootfs/etc/group
according to
group(5)
. For example:
archlive
/airootfs/etc/group
root:x:0:root
adm:x:4:archie
wheel:x:10:archie
uucp:x:14:archie
archie:x:1000:
Create the appropriate
archlive
/airootfs/etc/gshadow
according to
gshadow(5)
:
archlive
/airootfs/etc/gshadow
root:!*::root
archie:!*::
Make sure
/etc/shadow
and
/etc/gshadow
have the correct permissions:
archlive
/profiledef.sh
...
file_permissions=(
  ...
  ["/etc/shadow"]="0:0:0400"
  ["/etc/gshadow"]="0:0:0400"
)
After package installation,
mkarchiso
will create all specified home directories for users listed in
archlive
/airootfs/etc/passwd
and copy
work_directory
/x86_64/airootfs/etc/skel/*
to them. The copied files will have proper user and group ownership.
Keymaps
To change the live system's default keymap on the console, add a
vconsole.conf
with the desired keymap. Check
Linux console/Keyboard configuration
and
vconsole.conf(5)
for details and more options.
For example, to change the console's and X11's default keymap to German (
de-latin1
), create
archlive
/airootfs/etc/vconsole.conf
with the following contents:
archlive
/airootfs/etc/vconsole.conf
KEYMAP=de-latin1
XKBLAYOUT=de
Locales
To change the live system's
locale
, you must first enable and generate the localization files. For this to work you must add a custom
locale.gen
with the required locales and run
locale-gen
within the live system. This then enables you to also change the system's default locale.
For example, to enable
de_DE.UTF-8 UTF-8
and
en_US.UTF-8 UTF-8
, create
archlive
/airootfs/etc/locale.gen
with the following contents (check
Locale#Generating locales
for details):
archlive
/airootfs/etc/locale.gen
de_DE.UTF-8 UTF-8
en_US.UTF-8 UTF-8
You then need to run
locale-gen
within the live system. This can be achieved with a
Pacman hook
that is later automatically removed from the image by another hook. Create
archlive
/airootfs/etc/pacman.d/hooks/locale-gen.hook
with the following contents (check
Pacman#Hooks
and
alpm-hooks(5)
for details):
archlive
/airootfs/etc/pacman.d/hooks/locale-gen.hook
# remove from airootfs!
[Trigger]
Operation = Install
Operation = Upgrade
Type = Package
Target = glibc

[Action]
Description = Generating localisation files...
When = PostTransaction
Depends = glibc
Exec = /usr/bin/locale-gen
Optionally, you can then change the live system's default locale by adding a custom
locale.conf
. For example, to change the default locale to
de_DE.UTF-8
, create
archlive
/airootfs/etc/locale.conf
with the following contents (check
Locale#Variables
and
locale.conf(5)
for details):
archlive
/airootfs/etc/locale.conf
LANG=de_DE.UTF-8
Changing the distribution name used in the ISO
Start by copying the file
/etc/os-release
into the
etc/
folder in the rootfs. Then, edit the file accordingly. You can also change the name inside of GRUB and syslinux.
Build the ISO
Build an ISO which you can then burn to CD or USB by running:
# mkarchiso -v -r -w /tmp/archiso-tmp -o
/path/to/out_dir
/path/to/profile/
-w
specifies the working directory. If the option is not specified, it will default to
work
in the current directory. If memory allows, it is preferred to place the working directory on
tmpfs
(as shown above) to speed up the process.
-r
deletes the working directory (if it was created by
mkarchiso
) after successfully building the ISO.
-o
specifies the directory where the built ISO image will be placed. If the option is not specified, it will default to
out
in the current directory.
It should be noted the profile file
profiledef.sh
cannot be specified when running mkarchiso, only the path to the file.
Replace
/path/to/profile/
with the path to your custom profile, or with
/usr/share/archiso/configs/releng/
if you are building an unmodified profile.
When run, the script will download and install the packages you specified to
work_directory
/x86_64/airootfs
, create the kernel and init images, apply your customizations and finally build the ISO into the output directory.
Removal of work directory
Figyelmeztetés
If
mkarchiso
is interrupted, run
findmnt(8)
to make sure there are no mount binds before deleting it - otherwise,
you may lose data
(e.g. an external device mounted at
/run/media/
user
/
label
gets bound within
work/x86_64/airootfs/run/media/
user
/
label
during the build process).
Temporary files are copied into a work directory. If
mkarchiso
is run with the
-r
option, it will delete the work directory after successfully building the ISO as long as the directory did not exist beforehand. Alternatively, you can delete the work directory manually:
# rm -rf
/path/to/work_dir
Using the ISO
See
Installation guide#Prepare an installation medium
for various options.
Test the ISO in QEMU
Install
the optional dependencies
qemu-desktop
and
edk2-ovmf
.
Use the convenience script
run_archiso
to run a built image using
QEMU
.
$ run_archiso -i
/path/to/
archlinux-
yyyy.mm.dd
-x86_64.iso
The virtual machine can also be run using UEFI emulation:
$ run_archiso -u -i
/path/to/
archlinux-
yyyy.mm.dd
-x86_64.iso
Tips and tricks
Run setup commands as part of the ISO build process
When creating a custom profile, some modifications will require you to run setup commands within the live system's environment before creating the ISO. For example, if you want to enable additional locales, you must run
locale-gen
within the live system to generate the necessary localization files.
To run setup commands before creating the ISO, add a
Pacman hook
below
archlive
/airootfs/etc/pacman.d/hooks/
. Check
Pacman#Hooks
and
alpm-hooks(5)
for details on how to create custom Pacman hooks. Also check
#Locales
for an example.
Since these setup hooks are often required to run just once as part of the ISO build process, the
releng
profile includes a Pacman hook that removes any Pacman hook that is marked with the string
"remove from airootfs"
. So, if you don't want your Pacman hook to also apply on the running live system, add the following comment to your Pacman hook:
# remove from airootfs!
Prepare an ISO for an installation via SSH
Megjegyzés
Since
archlinux-2021.02.01-x86_64.iso
,
cloud-init support
is provided, and
sshd.service
is
enabled by default
.
To
install Arch Linux via SSH
without any interaction with the system, an SSH public key must be placed in
authorized_keys
.
Adding the SSH key can either be done manually (explained here), or
by cloud-init
.
To add the key manually, first
copy archiso's releng profile
to a writable directory. The following example uses
archlive
.
$ cp -r /usr/share/archiso/configs/
profile/
archlive
Create a
.ssh
directory in the home directory of the user which will be used to log in. The following example will be using the root user.
$ mkdir archlive/airootfs/root/.ssh
Add the SSH public key(s), which will be used to log in, to
authorized_keys
:
$ cat ~/.ssh/
key1
.pub >> archlive/airootfs/root/.ssh/authorized_keys
$ cat ~/.ssh/
key2
.pub >> archlive/airootfs/root/.ssh/authorized_keys
Set correct
permissions
and ownership for the
.ssh
directory and the
authorized_keys
file:
archlive/profiledef.sh
...
file_permissions=(
  ...
  ["/root"]="0:0:0750"
  ["/root/.ssh"]="0:0:0700"
  ["/root/.ssh/authorized_keys"]="0:0:0600"
)
Finally
build the ISO
. Upon booting the ISO,
OpenSSH
will start and it will be possible to log in using the corresponding SSH private key(s).
Automatically connect to a Wi-Fi network using iwd
Create
/var/lib/iwd/
inside the profile's
airootfs
directory and set the correct permissions:
$ mkdir -p
archlive
/airootfs/var/lib/iwd
archlive/profiledef.sh
...
file_permissions=(
  ...
  ["/var/lib/iwd"]="0:0:0700"
)
Follow the instructions in
iwd#Network configuration
and
iwd.network(5)
to create a network configuration file for your Wi-Fi network.
Save the configuration file inside
archlive
/airootfs/var/lib/iwd/
.
Gyökérfájlrendszer méretének módosítása
When installing packages in the live environment, for example on hardware requiring
DKMS
modules, the default size of the root file system might not allow the download and installation of such packages due to its size.
Tipp
See
BBS#210389
for the reason behind the chosen size, and
FS#45618
for historical details.
It will manifest as the following error message when downloading files or installing packages in the live environment:
error: partition / too full: 63256 blocks needed, 61450 blocks free
error: not enough free disk space
error: failed to commit transaction (not enough free disk space)
Errors occurred: no packages were upgraded.
To adjust the size on the fly:
# mount -o remount,size=
SIZE
/run/archiso/cowspace
See
tmpfs(5) § size
for the possible parameters of
SIZE
.
To adjust the size at the
boot loader
stage (by pressing
e
or
Tab
) use the boot option:
cow_spacesize=
SIZE
To adjust the size while building an image add the boot option to:
efiboot/loader/entries/*.cfg
grub/*.cfg
syslinux/*.cfg
The result can be checked with:
$ df -h
See
mkinitcpio-archiso boot parameters
.
Hibaelhárítás
Window manager freezes
If you want to use a
window manager
in the Live CD, you must add the necessary and correct
video drivers
, or the WM may freeze on loading.
