Subject: [PATCH] units: add remote-cryptsetup.target and
dd65c9
 remote-cryptsetup-pre.target
dd65c9
dd65c9
The pair is similar to remote-fs.target and remote-fs-pre.target. Any
dd65c9
cryptsetup devices which require network shall be ordered after
dd65c9
remote-cryptsetup-pre.target and before remote-cryptsetup.target.
