use group and user vars that don't conflict with rc.subr

frustratingly the var names I've chosen conflict with existing rc.subr ones :-( I need to rework these *again*

ensure default perms align with prior behaviour

speling

update after go port bump, reflow commit text

NB I would eventually like to fix this upstream too, but I have need of this functionality already.

going with ivy's opinion on this. thanks!

• move check earlier, I don't think I can use a hook this early
• actually works now

I still haven't figured out when the hook is triggered, but this is already pretty neat.

I pushed the rc update, but I'm not using it in the project I was planning to.

fix egregious errors in rc script

first draft of rc.d script

hi Moin,

LGTM. Over to doceng to bless with Macro Magic.

@ziaee thanks for the work on this, and everybody's comments. I think we are best committing this today
because its definitely better than what we currently have, and we can improve on that again as needed.

The FreeBSD-base url here needs to have the pkg+: prefix otherwise it doesn't work in our new CDN world. It seems simplest to just enable here, and let /etc/pkg/FreeBSD.conf specify everything else.

Ivy over to you if this should go into a set or not. This is a 1.12MiB package, with sysrc as well as bsdconfig.

committed in #1371b0ba8c

Just so we know this pulls in:

this commit was tagged relnotes but was missed previously. Also tidy up new jail syscalls that have manpage links. The jail_*_jd ones don't, so we can't fix them.

better title

package macro is for ports only sadly

update package per ziaae

add ziaee feedback

clarify preferred option, vs convenient option

Updated all but the`pkg add -f ..` bit. I hear what you're saying @cperciva but I have already encountered test users who are not comfortable with git, and I would like to give them a simple alternative with mostly familiar tools.

address all but pkg add -f ... feedback
