Flatpak uses OSTree, like Fedora Atomic Desktops (Silverblue, Kinoite etc) and similar to BTRFS snapshots.

So many files are deduplicated and linked, not actually there

      Those are unmaintained apps and you probably shouldnt use them. Poorly this is not as obvious and cant be enforced.

      One gotcha is installing both as user and root, getting two sets of dependencies. I only found out after a year or so of consciously using flatpak.

      I’m now taking care to make sure I only use flatpak as root. Maybe not the most secure.
