The best bet is to insure a quiet system.  Most implementations of
update() ("sync" internally) don't touch busy nodes...  So, you might
miss some unless the system is quiet.  Best to unmount all mounted
things first, too (this *will* insure all IO done (depending on
drivers, and particular UNIX in question)).  Since it's very hard to
tell just when inode "x" is in use from *outside* the kernel,
incantations of various sorts might be appropriate :-)

You're not paranoid if they *are* out to get you...
