Subject: Bug#1050040: /usr/bin/bup: "bup fuse" process lingers after unmounting

Package: bup
Version: 0.33.2-1~deb12u1
Severity: normal
File: /usr/bin/bup

Dear Maintainer,

When using "bup fuse", after unmounting the directory, the "bup fuse"
process lingers in the background and does not exit on its own.

> % ps x | grep fuse
> 327078 pts/7 S+ 0:00 grep fuse
> % bup fuse /tmp/bup
> % mountpoint /tmp/bup
> /tmp/bup is a mountpoint
> % umount /tmp/bup
> % mountpoint /tmp/bup
> /tmp/bup is not a mountpoint
> zsh: exit 32 mountpoint /tmp/bup
> % ps x | grep fuse
> 331964 ? Ss 0:00 bup fuse /tmp/bup
> 338467 pts/7 S+ 0:00 grep fuse
> % kill 331964

I don't believe this behavior existed in Debian bullseye; the "bup fuse"
process would exit normally after the directory was unmounted.

Thanks. I can trivially reproduce this here -- I'll plan to look in to
it.

OK, I have a very simple fix (though possibly not what we'll want in the
longer run). I'll plan to make a 0.33.x release in the next week or so,
and probably have the patch available sooner.

(Thanks to Johannes for help tracking it down.)
