[arch-projects] [mkinitcpio] [PATCH] Add sd-resume hook.

[Ivan Shapovalov]

This depends on the systemd hook. It adds systemd-hibernate-resume at .service
and systemd-hibernate-resume-generator which perform userspace parsing of
resume= kernel parameter, allowing to specify the resume device by its
persistent path ("resume=/dev/disk/by-foo/bar") or fstab-like specifier
("resume=FOO=bar"), just like the root= parameter.
---

Given that relevant functionality has just landed in systemd git, it makes
sense to pipeline things a bit (even if actual applying will be delayed until
systemd-217).

Also, does this need to be a separate hook or can be merged into 'systemd'
hook itself?
