Add me to the rel_mips group, and change the ownership of /space/releases-local/mips from root:root to root:rel_mips.
No one really SHOULD use that directory. Do you want experimental or releng. From the README: <snip> releases-local ================== Staging locations for BitTorrent, release and experimental media. Files pushed to here are NOT send automatically to the mirrors. You MUST contact an infra member to have them pushed. If you intent is to get files on http://distfiles.gentoo.org/releases/ then contact the releng team. </snip>
