So that you can have your own. pbuilder has one for inside the chroot, for
Write yours. If it is a generic useful thing for everyone, package it. Most
policy-rc.d I've seen to date are very very simple shell scripts, so why
bother packaging them?

Non-generic is not good enough to become infrastructure.
policy-rc.d can do what your veto-rc.d does, and much more.
Heck, the only thing you had to do was to rename your "veto-rc.d" to
policy-rc.d, and make it exit with status 101 when you wanted to veto
something, or status 0 otherwise... There is NO need to change ANYTHING in
the init script stuff, not in sysvinit, not in initscripts, nor in file-rc.
