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

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. --- install/systemd | 64 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 64 insertions(+) create mode 100644 install/systemd
