Thanks! While it is much more convenient to set it in one global
/etc/gitconfig than individual home directories, I encountered the
following problems:

1. It doesn't do anything with the other error I get, when the
problematic directory is '.'. I still keep getting that error message.
2. Git daemon doesn't seem to resolve the '*' wildcard, i.e. with the
wildcard I get the original message back which complains about
'/srv/git/mgsautils.git', despite it should be covered by
'/srv/git/*'. When I supply the full path, however, the error message
is still about '.'.

I even performed a whole Ubuntu release upgrade to get a new version
of Git, but 2.43.0 acts the same. Seems like git-daemon is more
stricts than plain git – what might be the problem?
