Just to say that I use LVM a lot, and LUKS also. Both have worked well
for me for many years with no problems. I also use btrfs but don't
particularly like it, but it does seem to be becoming more dominant.
Mixed filesystems are essential IMHO. I continue to use reiserfs until
it finally goes away, and I also use XFS. I don't much like ext2/3/4.
Snap & Flatpak I regard as the work of the devil so I've never used
them and can't comment.
