nspawn: add --image= switch to boot GPT disk images that follow the Discoverable Partitions Specification
nspawn: don't try mknod() of /dev/console with the correct major/minor

We overmount /dev/console with an external pty anyway, hence there's no
point in using the real major/minor when we create the node to
overmount. Instead, use the one of /dev/null now.

This fixes a race against the cgroup device controller setup we are
using. In case /dev/console was create before the cgroup policy was
applied all was good, but if created in the opposite order the mknod()
would fail, since creating /dev/console is not allowed by it. Creating
/dev/null instances is however permitted, and hence use it.
build-sys: Find the tools for users with no /sbin:/usr/sbin in PATH since some systems still make the distiction between bin and sbin.
rules: mark loop device as SYSTEMD_READY=0 if no file is attached

Check existence of loop/backing_file in sysfs and mark loop devices with
SYSTEMD_READY if missing. Such loop files is uninitialized and it's not
ready for use yet (there's no file attached).
update TODO
nspawn: make sure we don't try to mount the container block device in the child after the parent added us to the device cgroup
nspawn: when resoliving UIDs/GIDs for "-u", do so in forked off /usr/bin/getent instead of in-process

When the container runs a different native architecture than the host we
shouldn't attempt to load the container's NSS modules with the host's
libc. Instead, resolve UID/GID by invoking /usr/bin/getent in the
container. The tool should be fairly universally available and allows us
to do resolving of the UID/GID with the container's libc in a parsable
format.

dbus: suppress duplicate and misleading messages

When we try to send a signal on a connection we didn't hae the time to
process the Disconnected message yet, don't generate multiple warning
messages, but only a single debug message.

util: add files_same() helper function

files_same() returns
     1, if the files are the same
     0, if the files have different inode/dev numbers
 errno, for any stat error
systemctl: for switch-root check, if we switch to a systemd init

If "systemctl switch-root" is called with a specific "INIT" or
/proc/cmdline contains "init=", then systemd would not serialize
itsself.

Let systemctl check, if the new init is in the standard systemd
installation path and if so, clear the INIT parameter,
to let systemd serialize itsself.
man: multiple sleep modes are to be separated by whitespace, not commas

As pointed out by Jason A. Donenfeld.
man: fix description of systemctl --after/--before

It was backward - --after fetches After property, so units shown really
come *before* unit given as argument. Same for --before.
logind: add a debug message in case the session already exists

If the session already exists then the only way to log it is to set the
debug option of pam_systemd. There are no debug messages in the login
service that permits to log if the session already exists.

So just add it, and while we are it add the "uid" field to the debug
message that indicates that the session was created.
