Subject:   warning to cvsup users in "checkout mode"

People that are using cvsup to generate a "checked out" source tree 
without a local repository are going to see some pretty scarey looking 
warnings next time they update.  Assuming that all the preperation has 
gone right, it should resort to fetching the entire file rather than 
completely bomb out.  Apart from the fact that it is resending the file, 
it should be relatively harmless.

(What happened?  A long delayed "cleanup" of the cvs tree finally happened
over the last 12 hours or so.  Most of the things from my "must fix" list
are done, except for two kernel files.  The errors are caused by cvsupd's
inability to generate a diff to get from the old (no longer existing) head
revision to the new head revision.  This mostly affects src/contrib and src/
sys/netinet)

However, the checkout mode fallback code is known to trigger a cvsupd bug 
on the server for older cvsup clients.  It's important that the cvsup 
mirrors are running cvsupd 14.1.1, because 14.1 will core dump and abort 
the connection when a client triggers the bug.  If one of the mirror sites 
starts aborting connections on you consistantly, the odds are that the 
site maintainer didn't heed the warnings on the hubs mailing list that 
they are supposed to be subscribed to.

Naturally, this was timed to coincide with John Polstra going on holiday..
