The problem is that you have presumably dropped privileges in the daemon instance, but your $HOME environment variable still points to /root. Git cannot read all of its config files (nor even find out if they exist), so it bails rather than continue. Older versions of git silently ignored errors reading config files, but it was tightened in v1.8.1.1, as there can be quite serious implications to failing to read expected config (e.g., imagine transfer.fsckobjects, or receive.deny* is ignored). However, since changing user id and leaving $HOME is so common, there is a patch under consideration to loosen the check only for the case of EACCES on files in $HOME. That commit is 4698c8f (config: allow inaccessible configuration under $HOME, 2013-04-12); it's not yet in any released version of git, though. In the meantime, the suggested workaround is to set $HOME for the git-daemon user, rather than loosening /root. -Peff -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
