[BUG] mount.fstab_present (etc.) should treat overlay as a special filesystem too #66912

Description
There is special logic in Salt to intelligently match a requested state to existing /etc/fstab entries (the auto value of match_on). It has an internal list of file systems where matching should be done on the target directory (aka fs_file) instead of the source device (aka name).

However, overlay (Linux's OverlayFS) is not on that list, resulting in fstab entries being overwritten if you don't manually change the matching by specifying match_on: name. (Please don't get confused, here name actually means target, even though in the YAML name is the source.)

Setup

  • on-prem machine
  • onedir packaging
  • masterless
  • Linux
  mount.fstab_present:
    - name: overlay
    - fs_file: /tmp/merged
    - fs_vfstype: overlay
    - fs_mntops: lowerdir=/tmp/ro,upperdir=/tmp/rw,workdir=/tmp/work
#   - match_on: name
