Please understand that I haven’t tried or installed Arch Linux yet. From what I understand by reading and watching related videos, Arch is often breaks and a lot of time is required to fix issues. But I have also read comments from arch users who claim that arch has only crashed or caused them problems only a couple of times in a year.
Wouldn’t a stable or non rolling release distro be a great choice for the Steam Deck?? Also, how frequently do the packages get updated on steam os?
For the same reason Chromebooks use Gentoo Linux. It fit their workflow in development an immutable OS.
There are a few hang ups an end user might encounter but with an immutable OS it’s been thoroughly tested before reaching the user.
At the end of the day Linux is Linux and it doesn’t really matter what you build your system on. If properly tested, it’ll be rock solid.
