Re: [PATCH/RFC 0/4] Providing mechanism to list available repositories

quoted

We find this mechanism useful in that it requires no extra
infrastructure on either our end or the user's end.  Our
implementation is extensible, allowing the system administrator to
place arbitrary commands in ~/git-shell-commands (if the directory is
omitted, no extra functionality is exposed), and also supports an
interactive mode.

What do people think of this approach?  I'd love to get this
functionality merged in some form.

It seems to me that any time you need to add a new helper command, the
administrator needs to make sure that appears in ~$user/git-shell-commands
of all the users who need it.  When adding a new user, a similar
management action needs to happen.  Perhaps that is done by making a
symlink from all the users' home directories to one shared place.  Is that
the general idea?

That's correct.  Our particular environment only has a single git
user, but if we were to add more we would probably make
git-shell-commands a symlink as you suggest.

In any case, I'd prefer that the sample command implementations like list
and help to live in contrib/ somewhere.  They are not part of what the
main Makefile needs to know about, right?

Also correct.  I'll look for a reasonable place within contrib/ to put them.
