Subject: [PATCH 8/8] swap: create .wants symlink to 'auto' swap devices
|
|
|
|
As we load unit files lazily, we need to make sure something pulls in swap
|
|
units that should be started automatically, otherwise the default dependencies
|
|
will never be applied.
|
|
|
|
This partially reinstates code removed in
|
|
commit 64347fc2b983f33e7efb0fd2bb44e133fb9f30f4.
|
|
|
|
Also don't order swap devices after swap.target when they are 'nofail'.
