Remaining service after uninstall of app-emulation/snapd

After uninstall

systemctl list-unit-files | grep -i snap

snap-ubuntu\x2dcore-423.mount

systemctl -all | grep -i snap

snap-ubuntu\x2dcore-423.mount loaded active mounted Mount unit for ubuntu-core ● snapd.socket not-found active running snapd.socket

snap-ubuntu\x2dcore-423.mount remains after reboot

After Install

systemctl -all | grep -i snap

Is snap-ubuntu\x2dcore-423.mount from the snap-confine package, or does it come from installing a snap package (I've been using nitrokey-app)? I didn't see it in the src_install portion of the snapd package.

The .mount unit is from snapd. Each installed snap is just a mounted filesystem. I think we should either:

1. remove everything (all the snaps, their data, etc)
2. keep everything as is

The difference is visible when you re-install snapd. After that you can just continue as if nothing had occurred earlier. If we o with 1) we'd have to carefully stop all the snap services (services from installed snaps). Stop snapd, unmount everything and remove all the generated services and mount points.

I will test with manually uninstalling my snaps prior to unmerging the packages. If that successfully cleans things up, then maybe I'll put a notice (gentoo packaging metadata) to instruct users to do just that (if they want) - or leave them for a future re-install.

Thanks!

Even after uninstalling any snaps, snap-ubuntu\x2dcore-423.mount remains. I think ubuntu-core is installed along with the first snap package, but isn't removed when all snaps are removed. I'd prefer if either unmerging snapd removed everything - or if we could include instructions for the user on how to manually umount, disable services, and clean up the files.

What are your thoughts?

[zyga]

I think it should remove everything. We're still working on features for the next major release but after that I will work on packaging to address this (and many other issues). I will try to get this fixed in time for the snappy sprint next week.
