@drinkcat: Use useradd instead of adduser to avoid pointless prompts.

Thanks, @drinkcat!
Move timezone sync earlier, into core target.
No, we don't want to run hddtemp as a daemon.
Move ubuntu to separate directory.
New wrapper installer script.
First working Arch Linux version. More testing needed.
Support for "touch" target.
Install croutoncursor.
Fix croutonwheel by using mawk (Arch uses gawk by default).
Fix startxfce4 on host by adding /usr/local/bin in /etc/login.defs
Updated installer.
Use -e instead of -x in installer (prevent problems with noexec).
Update documentation.
Add --noconfirm to most pacman commands.

Install xorg-init before updating /etc/X11/xinit/xserverrc .
Switch back to sh for installer.sh (use shift instead of bash-specific variable to pass arguments).
Use "$@" instead of $@ to pass parameters, just in case.
Use xmodmap to map Search+backspace and Search+arrows keys (respectively delete and home/end
page up/down) like in Chrome OS.
Add Search+. and Search+Alt to xmodmap: respectively Insert and Caps Lock. Insert will break on
non-US keyboards.
Add xmodmap support in arch target.
- Update arch post-common to create localtime symlink.
