Subject: [PATCH] shared/install: allow "enable" on linked unit files
|
|
|
923a60 |
|
|
|
923a60 |
User expectations are broken when "systemctl enable /some/path/service.service"
|
|
|
923a60 |
behaves differently to "systemctl link ..." followed by "systemctl enable".
|
|
|
923a60 |
From user's POV, "enable" with the full path just combines the two steps into
|
|
|
923a60 |
one.
|
|
|
923a60 |
|
|
|
923a60 |
(cherry picked from commit f777b4345e8c57e739bda746f78757d0fb136ac7)
