avoiding ~/.procmailrc

Is it possible to convince procmail not to read the ~/.procmailrc file ?
I'd like to move users' .procmailrc files from their home directory to some
special /var/something directory to avoid the mail server having to access the
users' home dirs which are mostly on a remote machine (which is sometimes down,
of course). Since procmail starts by reading the /etc/procmailrc, I figured I
could add something like "INPUTRC /var/somwhere/$LOGNAME" in it, but how
can I make sure procmail doesn't then try to access ~/.procmailrc ?

Of course, I can hack the source, but I'd rather not do it.
