$ grep -l update-rc.d /var/lib/dpkg/info/*.postrm|wc -l

When you say it's a "nasty" bug, do you mean this assumption actually broke

I think the requirement that Essential: yes packages be usable when unpacked
but not configured implies that their dependencies must also be minimally
usable when unpacked but not configured, doesn't it?
