I'm not sure; I think that depends heavily on circumstances, what the
production machine does, and what happens if it breaks. E.g. on a
department mail server, a five minute downtime on a Saturday night to
rebuild and reinstall spamassassin isn't going to cause a problem; if
it fails partway through, you undo-replace.

Doing a full steam_roller during a scheduled downtime of a production
machine (especially, doing it blindly) is probably unwise, but that's
a different matter from doing a series of preplanned replaces.

oh, and btw, "make update" does have some bugs.

That makes far too much sense... :-)
