Bug Description

Hi,
our regular metric checks found a 4mb increase of disc consumption.

I've found that comparing
from
74e72ff5c7af | yes | ubuntu 23.10 amd64 (minimal daily) (20230614
to
c61eed8b36a0 | yes | ubuntu 23.10 amd64 (minimal daily) (20230618)

both from https://cloud-images.ubuntu.com/minimal/daily/

No packages changed, but /var/cache had ~4mb more.

I found that this is due to /var/cache/snapd/commands.db now being present.

The other commands.db like /var/lib/command-not-found/commands.db are stripped in those images, so I guess It should be done here as well?

I'd appreciate if you could have a look if this is intentional or just fallen through the crack and need to be stripped.

curious, an examination hasn't brought much to life why it started being added.

I'm also not seeing where the commands.db is removed normally. for Minimal, there's a dpkg-filter for man pages but i'm not seeing commands.db

https://git.launchpad.net/livecd-rootfs/tree/live-build/auto/build#n183

This needs a deeper look, because something is off _somewhere_, but i can't find a diff as to what may have changed, or the location where we remove other commands.db in a minimal image (at least within livecd-rootfs)

Yeah, I saw this file even being added between images with zero package diff at all.

Hence I assumed it would be part of the build/filtering process on your side.
Since you agreed, I hope you do not mind me setting that to confirmed then.
