I've noticed some different messages when I do apt install in my butterknife 2.28 install versus one from last week.

Good news, nothing's broken. Snapshots are getting made and the GRUB snapshot menu is updating fine, there are no errors in there. It's just gotten chatty.

Quick rundown of the noise:

"Quotas are not enabled" is Timeshift poking at btrfs to check snapshot size. I leave that btrfs feature off (it slows things down and we don't need it), so btrfs just says so. Harmless.
"Detecting / Found snapshot" and the "Unmount... Success" at the end is the GRUB menu rebuilding itself after the update. To list your snapshots it briefly mounts the drive read-only, looks around, then unmounts and cleans up.

Read-only, so it can't change anything.

Basically it's just narrating its own chores out loud. I told it to do that part quietly instead. Fixed in 0.2.9 (which also fixes #6).

Thanks!

just installed with 0.2.9. everything looks good. Still some extra noise when you install an apt package, but like you said. no harm/no foul.
