Subject: [PATCH 1/7] osbuild: use path as secondary sort key for fstab
|
|
|
|
Most filesystems entries in fstab don't have a PassNo, which makes the
|
|
order of those entries dependent on the sorting algorithm. Changes in
|
|
the algorithm can introduce changes in the sort order, which we don't
|
|
like.
|
|
|
|
Add a secondary sorting key, the Path, which is guaranteed unique, to
|
|
guarantee stable ordering.
