It's in section 6.3, point 3. When 'new-preinst install old-version'
fails, 'new-postrm abort-install old-version' is called; when
'new-preinst install' fails, 'new-postrm abort-install' is called. So if
your preinst's install step calls useradd, you should unwind that with
userdel in the postrm's abort-install step.
