Subject: [PATCH] systemctl: allow disable on the unit file path, but warn |
|
about it (#3806) |
|
|
|
systemd now returns an error when it is asked to perform disable on the |
|
unit file path. In the past this was allowed, but systemd never really |
|
considered an actual content of the [Install] section of the unit |
|
file. Instead it performed disable on the unit name, i.e. purged all |
|
symlinks pointing to the given unit file (undo of implicit link action |
|
done by systemd when enable is called on the unit file path) and all |
|
symlinks that have the same basename as the given unit file. |
|
|
|
However, to notice that [Install] info of the file is not consulted one |
|
must create additional symlinks manually. I argue that in most cases |
|
users do not create such links. Let's be nice to our users and don't |
|
break existing scripts that expect disable to work with the unit file |
|
path. |
|
|
|
Fixes #3706. |
|
|
|
IMPORTANT |
|
========= |
|
Note that in this downstream backport we actually pass false to |
|
normalize_names(), hence it will not produce any warning when full path |
|
is passed in. This is because we need to preserve behavior compatible |
|
with prior systemd versions shipped in RHEL. |
