commit d2c68822c47e37b582820f45b496b2e7d1f9e642
Author: Ivan Shapovalov <intelfx100 at gmail.com>
Date: Wed Aug 27 00:17:45 2014 +0400
hibernate-resume-generator: add a generator for instantiating the resume unit.
hibernate-resume-generator understands resume= kernel command line parameter
and instantiates the systemd-resume at .service accordingly if it is passed.
This enables resume from hibernation using device specified on the kernel
command line, and it may be specified either as "/dev/disk/by-foo/bar"
or "FOO=bar", not only "/dev/sdXY" which is understood by the in-kernel
implementation.
So now resume= is brought on par with root= in terms of possible ways to
specify a device.

commit 42483a747489ff46aed3588b78bf4b9480dbeaf7
Author: Ivan Shapovalov <intelfx100 at gmail.com>
Date: Wed Aug 27 00:17:44 2014 +0400
hibernate-resume: add a tool to write a device node's major:minor to /sys/power/resume.
This can be used to initiate a resume from hibernation by path to a swap
device containing the hibernation image.
The respective templated unit is also added. It is instantiated using
path to the desired resume device.
