Not necessarily.

And, if sysklogd *is* purged before the rsyslog postinst runs, then there's
no cleanup needed - sysklogd postrm removes the user, rsyslog postinst
re-adds the user, no problem at all.

So this should simply be:

  if [ -e /var/lib/dpkg/info/sysklogd.postrm ]; then
   sed -i -e'/deluser/d' /var/lib/dpkg/info/sysklogd.postrm
  fi

in the rsyslog postinst, before the #DEBHELPER# block that starts the
service.

If that *doesn't* work, then there's another bug going on; rsyslog shouldn't
be started before its postinst has run.

Could be done, but I think it's better to keep the quirk local to the
affected packages (i.e., we only care about this in the case that sysklogd
is being removed and rsyslog is being installed, so rsyslog can just as well
do the same thing that update-manager would in its stead).
