Yes, this is what we'll try:
- rsync, *not* additively (i.e. with deletions) from our chosen main
mirror site (currently incomplete for about 2 months),
- run md5cycgchk on our local mirror
- if that shows an incomplete mirror:
- rsync *additively* from another site
- run md5cygchk on the result.
- Maybe repeat once or twice with other sites if still needed
(i.e. mirror still incomplete).
This way obsolete packages will eventually get pruned when the main
mirror site gets corrected, and even if one or a few sites don't mirror
properly from cygwin.com, even for a long time, we can still create a
complete mirror (with high probability).

PS:
md5cygchk is just a script that checks if all packages are present and
correct according to the md5sum files, and records the result in a
success or fail text file that can be checked for: even from a dumb
Windows batch file.
