Re: [RFC][PATCH] Rewriting revs in place in push target repository

Petr Baudis [off-list ref] writes:

Rewrite refs in place in receive-pack & friends

When updating a ref, it would write a new file with the new ref and
then rename it, overwriting the original file. The problem is that
this destroys permissions and ownership of the original file, which is
troublesome especially in multiuser environment, like the one I live in.

Hmph.  If a repo is _really_ used multiuser then you should not
have to care about ownership.  If you can write into a
repository for a project (implying that you are a member of that
project group), and if your umask is set up correctly (meaning
it is 002 or looser), and with g+s bit on the directory at the
repository root level when it was created, shouldn't your newly
created ref file be also writable by others in that project?
