guess why ;)

if you want to fail in a 'hard' way, yes.
the problem is: any package should at least be installable, so it could be
checked by automatic deb checkers as piuparts; it just shouldn't do anything
harmful ;)
if put /sbin/start-stop-daemon.fai into the package and dpkg-divert and
symlink it in postinst (depending on something, be it a debconf answer or a
file somewhere), you are on the safer side...
