There’s a very outdated wiki on GitHub regarding the status of snap confinement by distro: https://github.com/snapcore/snapd/wiki/Distributions/b62468b413b2c82da0a5d21c5e07fe03c25a4960
At a glance, based on this user’s issues it looks like there’s been movement regarding confinement since the wiki was last updated - cgroups, bpf, etc. example: Cannot start some applications after upgrade to snapd-2.53.1 on OpenSuse Tumbleweed
I’m trying to see if they’ll start supporting snap ecosystem officially over there, and I think confinement was the sticking point (way back in 2017 when canonical first approached Opensuse AFAIK). Reference: https://build.opensuse.org/request/show/601690
Additional references - discussion on Opensuse Subreddit: https://www.reddit.com/r/openSUSE/comments/as8ouz/where_can_i_find_discover_snap_backend/
Maybe making some of the updates apparent in the Wiki would help the process, in addition to re-submitting to Opensuse:Factory with updates (the submission made back in 2018 is still current in snappy repo, but doesn’t look like it’s been updated and re-submitted to the factory repo to make it official).
I’m not sure I’m qualified to re-open submission to Opensuse:Factory but I could probably PR the Github wiki if someone wants to give me the progress info
If anyone else has any info I am not aware of, or has a better way to go about this, please let me know.
