Immutable might be fine for a single-purpose OS like SteamOS but it felt like jumping through hoops just to get basic packages installed and added to PATH without writing to root. Using a mutable distro with BTRFS snapshots has been the best of both worlds for me, I get to modify and install to root as I please and whenever anything goes wrong I just revert back to a previous snapshot and get a working system again.

- No Fcitx: Sorry, but there are more native Chinese speakers than native English speakers, having an IME is not an excessive luxury (and please, don't use Ibus, that garbage is horrible).

I'm glad someone else gets it. I swear the only reason it sticks around is because the people who call the shots on most distros speak non-IME languages like English and German to which IBus "gets the job done". If you speak a language that requires an IME (Chinese, Japanese, Korean, etc.) then it's just an painfully buggy experience and you'd be much better off with Fcitx 99.9% of the time.
