Genuinely curious: what don't you like about flatpaks?
I find that flatpaks are quite awesome, because you can have any distro, while all apps continue to work (but I'm also not a dev or anything, so don't know about that side of the story).
Yesterday I tried to format and encrypt a usb drive, accidentally encrypted the main drive and it wouldn't boot to a snapshot before that. Decided to go for EndevourOS (Arch BTW) instead of Tumbleweed because I found Tumbleweeds installer too complicated.
The clidren yearn for the mines.
