Yes, I had an override in systemd that I'd forgotten about to work
around a previous issue (because the previous version we had on the
machine required the paths on the end of the git-daemon command line.)

I wonder if there was a bug - --export-all broke, and then required the
directories to be listed, and now it's been "fixed" and now the listed
directories become a list of those to exclude?

The override.conf had something like:

ExecStart=-/usr/libexec/git-core/git-daemon --export-all \
  --user-path=public_git --inetd --log-destination=stderr --verbose \
    --interpolated-path='/var/lib/git/%%H%%D' \
    /var/lib/git/git.armlinux.org.uk \
    /home/rmk/public_git

I can't remember exactly now as I've deleted the last two paths, and
added --base-path=/var/lib/git - and now it's working.
