psd fails if /sbin or /usr/sbin is not in PATH #217

Closed JanLuca closed 6 years ago

JanLuca commented 6 years ago

In profile-sync-daemon there are multiple calls to modinfo. This calls fails if /sbin or /usr/sbin is not in PATH. Could you use the absolute path to the tools used so they do not depend on the environment?

Thank you in advance, Jan

The script depends on many dependencies being in the path, for example, rsync, awk, modinfo, etc. I am trying to imagine a setup in which one would not was those paths in the global $PATH...

The issue is rather, that the calls to modinfo fail if /usr is not merged. On arch modinfo is situated in /usr/bin and not in /usr/sbin, where it is in Debian, and /usr/sbin is not necessarily in the $PATH for historical reasons.

Could the hard dependency on modinfo maybe avoided if the overlayfs feature is not used?

Having debuged the problem a bit further the problem is a bit less clear. We will report back with more info.

I don't understand that.... if you put modinfo in /foo/bar and if /foo/bar is in your path, it works. If not, it doesn't work. Your global vars don't seem to be right for whatever reason.

On debian modinfo is in /sbin, which is not in a normal user's path.
