back in the days of 1.82 when we first started we got problems, so the
configure change program now looks like this (the new configure file is stuffed
into incoming, and we run a Makefile which thus only updates the live service
when a change occurs):
cp configure configure.old
cp -p incoming/configure configure
chown root configure
chgrp other configure
chmod g=r configure
kill -1 `cat /var/spool/exim/exim-daemon.pid`
it's belt-and-braces, but our occasional outages stopped happening...
