echo 3 >> a; git commit -a -m2
cp -a .git sub

git --bare config --bool core.bare true

I think what is happening is that in that bare repository 'sub',
the sequence we find where a git repository is is defined so
that the current directory is checked way after "one of my
parents with .git/ subdirectory" check.
If super (a directory) has a subproject sub as its subproject,
then you would be copying .git to sub/.git, not sub/, wouldn't
you? What are you trying to achieve?

Yes, that's what I found. Couldn't convince myself it could be wrong,
feels right to me.

Yes, very likely. But it is not a super project in subproject sense,
and why? Is there a reason I can't have a bare subproject?
What are you trying to achieve?
I mirror some projects I am interested in. There is a directory where
all the mirrors are: ~/src. It contains the git/git-svn/git-cvs
repositories _and_ the scripts which do the mirroring:
$ ls -a
./ gitk/ motion.gitsvn/ uclibc.gitsvn/
../ gnulib.git/ moto4lin/ udev/
busybox.gitsvn/ gpsbabel.git/ mutt/ udhcp.gitsvn/
coreutils.git/ historic/ rt2500/ update-gits*
count-git-objects* .htaccess sparse/ use-src/
dclock/ iproute2.git/ sunset/ wireless-2.6.git/
git/ klibc/ tig/
.git/ linux.git/ torsmo/
.gitignore mimesplit3/ tuner/
The super in my example is this ~/src, and it keeps track of changes
to the scripts (some mirrors can be complicated, so I wanted to be
prepared). Felt kind of natural to do it this way. Until I tried to
repack the mirrored repos, and it didn't work as I expected. The repos
are not tracked as subprojects (in fact, they're .gitignored).
There is no point for me to have working directories for the mirrors:
it is my home server, if I do something, I do it elsewhere.
It is not exactly a "problem", and anyway there is a couple of
solutions (pass --bare, create <mirror>/.git, for instance), I just
fall into it and though it'd be a good idea to let others know.
