Makes sense that it includes snap given that KDE officially supports their apps packaged as snaps, unlike Gnome.
If I recall correctly, aren’t they going for an Arch base? I assume they’re going to be enabling AppArmor so that the snap sandboxing is mostly working, except for the patches Canonical have failed to upstream so far.
Yes it is an Arch base. Not sure on the apparmor stuff and snap is basically banned from the Arch repos so it's relegated to the AUR which makes it a pain.
