#3079 PR `merged`: Don't mount /sys and other directories if already mounted¶

Labels: enhancement, bug, fixed / solved / done

Type: Bug Fix
Impact: High
Reference to related issue (URL): fixes #3017
How was this pull request tested?
CI tested it - I enabled tests on Fedora 39 and Fedora Rawhide
Description of the changes in this pull request:
Newer versions of systemd (starting with Fedora 39) seem to mount /sys themselves. Mounting it again leads to errors on the recovery system startup (startup scripts failing with status=219/CGROUP ), see https://github.com/rear/rear/issues/3017.

Check if /sys is already mounted using the mountpoint tool and mount it only if it is not.

Do the same for the other system mountpoints like /proc, /dev, /dev/pts. Not sure if they suffer from the same problem, but they probably could.

N.B. the mountpoint command is already among REQUIRED_PROGS.

Forece pushed to correct a typo in commit message, no code changes.
