Subject: units: add remote-cryptsetup.target and remote-cryptsetup-pre.target
X-Git-Tag: v235~158^2~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=889128b8b27abb13e1691a72e4ce0562c564e257;p=platform%2Fupstream%2Fsystemd.git

units: add remote-cryptsetup.target and remote-cryptsetup-pre.target

The pair is similar to remote-fs.target and remote-fs-pre.target. Any
cryptsetup devices which require network shall be ordered after
remote-cryptsetup-pre.target and before remote-cryptsetup.target.
