Well, we could by default install S* and K* files, except if the
<pkg>_INIT_SYSV_FILES variable is defined, in which case we only
install the ones that are mentioned. Maybe it's making the logic too
complicated, I don't know.

For systemd, I would expect the package build system to install the
unit files by itself, no?

And for init scripts, we generally don't use the init scripts provided
by the package itself, because they're often too complicated / not
compatible with the simple Busybox init.

But, well, maybe you're right and making things explicit is better.
