Subject: [PATCH 1/1] Revert "job: Don't mark as redundant if deps are
|
|
relevant"
|
|
|
|
This reverts commit 097537f07a2fab3cb73aef7bc59f2a66aa93f533, which involves a
|
|
significant behavior change which at least impacts plymouth [1] and some of the
|
|
services shipped by systemd (systemd-vconsole-setup.service).
|
|
|
|
Of course some other units shipped by other packages might rely on the old
|
|
behavior [2], which makes me wonder why this patch wasn't simply reverted until
|
|
the situation gets clarified, at least that what the author of the change
|
|
thinks too [3].
