There's of course dependencies in OpenRC. You have the choice: either
you keep the LSB headers, either you write it the OpenRC way (IMO,
prefered...). In OpenRC, you just use functions of the openrc-run
"interpreter". For exaample:
depend()
{
use dns
need localmount
after bootmisc ntp-client
}
The "need" expresses a Required-Start:, and "use", a Should-Start:.

cgroup are optional, and obvious, not in use in kFreeBSD (see
/etc/rc.conf for its activation).

Sorry, I don't know. You can try if you're curious! :)

Correct, and I agree. The /sbin/init binary is anyway very small. As
much as I can tell, it is built only out of src/init.c and src/utmp.c,
which together represent 3162 lines of C code currently. That's antic
code from 1991! :)
