Feature Request: Allow multiple POST snapshots w.r.t. an existing PRE snapshot about snapper

[aschnell]

It is a 1:1 mapping between pre- and post-snapshots. I do not like to change that. How should the empty-pre-post cleanup and the list with --type=pre-post work in that case? Likely there are more problems.

What could maybe be done is a new option to remove the pre number from the old post-snapshot.

I understand that snapper

• under the hood makes use of the btrfs tool set and other tools like, maybe, diff
• adds snapper specific information in the files /.snapshots/NN/info.xml

So, would it be possible to have the snapper GUI* provide diffs between arbitrary /.snapshots/NNs?

In such case the pre and post tags are still a very helpful feature to document explicit snaphot-protected activities - but basically nothing special for the diff mechanism?

• snapper CLI does it
