Subject: [PATCH] units: add remote-cryptsetup.target and
|
|
|
17b0f1 |
remote-cryptsetup-pre.target
|
|
|
17b0f1 |
|
|
|
17b0f1 |
The pair is similar to remote-fs.target and remote-fs-pre.target. Any
|
|
|
17b0f1 |
cryptsetup devices which require network shall be ordered after
|
|
|
17b0f1 |
remote-cryptsetup-pre.target and before remote-cryptsetup.target.
