By default, /home is a subvolume of / on the same partition, so it’s possible that if the partition for / were reformatted, that /home might have gotten blown away with it. If that’s the case, then the Blivet UI needs to be more obvious that this is the likely result. As always, I strongly recommend you backup your data before attempting a reinstall like this with any filesystem.
Thanks – but I would have understood having all of /home blown away. What I’m puzzled by is the way only those files in /home which were created after the last full install were deleted; all the files older than the initial Fedora 36 installation are still there.
And, yes, backing up is a good idea – even if you’re not attempting a reinstall.
