Required: yes. The highest priority. sysvinit was Required: yes until
systemd came along https://www.debian.org/doc/debian-policy/#priorities

Speaking of, I can't use 'apt-get indextargets' from shell and had to
rewrite in ruby, because sed doesn't not support lazy matching, and I don't
know how else to match NOT \n\n. (it also doesn't seem to support multiples
of submatches.) Old regular expression implementations are showing their
age (not to mention perl's non-regular features).
