The layout could be like this then:

package moves between repos.
The negative side is that this will need one-time redownload of all

(need to be done in this way: wait until /all syncing starts, kill rsync,
move packages manually, start rsync).
BTW I always wondered why we have that silly "os" subdir.
Would be nice to get rid of it during this big mirroring change (if
