Scheduled updates to the master also have the other advantage I
mentioned; it'd greatly help here.

I'd rather the /fullfilelist was completed with the necessary info. As
it is now it's useless but if properly done would avoid full scans
upstream; downstream pulls /proper-fullfilelist, sees what's changed
and pulls only what it needs. At the end of the update it puts the new
version of the filelist in place so that further downstreamers can do
the same.
