<pre>Observed behavior:
[bob@a00:~]$ sudo systemctl enable /foo/bar.service
Failed to execute operation: Invalid argument
Expected behvaior:
[bob@a00:~]$ sudo systemctl enable /foo/bar.service
Unable to create symbolic link /etc/systemd/system/bar.service: target already
exists
Details:
It seems that the systemd code generally passes error information as a single
numeric code, even across contexts where the caller cannot know what the error
code applies to. This problem is further exacerbated by systemctl itself not
doing any work; attempting to run systemctl under strace will not reveal
additional context.
I would suggest making a per-thread error description string that takes
precedence over errno if set, maybe something like this:
