I did basically:
git clone --reference ~otheruser/nongnu
[ Days passed and I did various things. ]
cd nongnu; git gc
Note that `otheruser` is [..wait for it..] another user, so I only have
read access to the referenced repository.
> What did you expect to happen? (Expected behavior)
That it would GC the local part of the repository and that it wouldn't
try to modify the referenced repository.
> What happened instead? (Actual behavior)
I got warnings indicating that Git was trying to delete files from
the referenced repository:
Enumerating objects: 35095, done.
Nothing new to pack.
warning: unable to unlink
'/home/otheruser/nongnu/.git/objects/pack/pack-0d85e74ac2f7e51ce26f281e64eb738e8182fa95.idx':

The warnings.

The warnings make me wonder if I should worry about other possible
misbehaviors when using such a setup.

This is on a Debian stable system but with Git from Debian testing
(because the version from Debian stable crashed in a `git log` command
I was using in my scripts).
