rcp and st_mtime

[stanonik at nprdc]

We maintain a common /usr/lib/aliases on one machine and propagate
updates to other machines by
	cd /usr/lib
	rcp aliases* othermachine:/usr/lib
Sometimes after doing this, sendmail on othermachine warns that
the "database is out of date"; ie, aliases is newer (st_mtime) than 
aliases.pag.  csh sorts expanded filenames alphabetically, and rcp 
handshakes (ga/response) between file transfers.  Any ideas why the
st_mtime's don't reflect the order of transfer?  Maybe it has something
(everything) to do with aliases.pag on othermachine sometimes being
in use during the transfer?

Thanks,
