Problem with this is, that unless special care is taken to do it this 
way, we can't rely on the repository metadata to be updated last.

I still vote for adopting the debian way - add a

	if test -f /path/to/mirror/trace/$(hostname); then
		rm -f path/to/mirror/trace/$(hostname)
	fi

to the start of the sync script, and a

	date > /path/to/mirror/trace/$(hostname)

to the end...

(obviously, the code would have to change to reflect the public mirror 
name, if different from $(hostname) and such, so this is just an example 
of how easy something like this could be.

When syncing against ftp.giantmirrorsite.com, we can check for the 
"ftp.giantmirrorsite.com" file in the trace directory. If it's there, we 
can relatively safely assume that the mirror is in sync. The contents of 
the file would indicate the time of last sync completion and the other 
contents of the trade/ dir reveals the path the updates has traveled 
downstream. Very nice.
