[arch-projects] [mkinitcpio][PATCH v2] [WIP] systemd: add systemd hook

[Tom Gundersen]

Note: generate initramfs with
 HOOKS=('base' 'systemd' 'autodetect' 'block' 'filesystems')

This relies on patches patches soon to be posted on the systemd mailinglist.

This hook would live in the systemd package, but posting it as a mkinitcpio
patch because SVN.

Ideally, we would eventaully introduce "add_unit" and "add_rules" functions that
would allow us to add a few udev rules and systemd units, and have
everything else
in this hook (e.g., binaries from RUN= or ExecStart= and other units based on
Wants/Requires dependencise) pulled in automatically.

v2: don't parse /sysroot/etc for new settings
