I nfs-mount /usr/portage (ro) and /usr/portage/distfiles (rw) from my storage server on all my machines. I wrote an emerge-fetch script which checks /etc/portage/old/ (a symlink) before trying mirrors (moving if permitted, copying if not), so I can clean up unused downloads by moving everything to distfiles/old, then doing emerge -ef world on all my boxes. I'm sure others could find numerous uses for a filesystem-based mirror uri. Reproducible: Always Steps to Reproduce:
Created attachment 106882 [details] /usr/local/sbin/emerge-fetch my emerge-fetch script if anyone wants it
Dunno what you are after, but GENTOO_MIRRORS="/usr/portage/distfiles" works just fine...
We need to document the filesystem mirrors functionality...
I've added a note to make.conf.5 in svn r5644.
