Huh. They're on the same ext4 fs (it's an AWS EBS sc1 volume, but I think that still counts as "not a network mount" as far as Linux is concerned.)

The way I was seeing this fail was a CGI invoking "git push", as user "httpd" (and I verified that when the cgi was invoked, "groups" reported that "httpd" was a member of group "cvs") but when I tried to reproduce the error with "sudo -u apache git push" it didn't fail. So possibly something hinky is going on with group permissions when httpd invokes git, but I did verify that whoami, groups and pwd were as expected, so I couldn't tell what that might be... (Oh, I didn't check what umask was, but it should have been 022...)
