Yes, 'make restart' won't work in all cases, so we should settle for
[stop] -> deinstall -> reinstall -> [start]
[Or hand in one of your pointy hats for devising a mechanism to tell by
OLD_PORTVERSION vs. NEW_PORTVERSION whether restarting or reconfiguring
is required]
Back to the features -- for control, I suggest two knobs:
RC_RESTART and ${PORTNAME}_RC_RESTART?=${RC_RESTART} which have to be
explicitly enabled. RESTART is a bad name, though, since it suggests
"restart". RC_POWERCYCLE would at least be obvious to every reader but
clearly isn't suitable.
pkg_add should honour this as well. Even if you enabled RC_RESTART: Since
for RCng you didn't yet enable the service in rc.conf, nothing bad happens
(e.g. kris coming down on us :).
How does this all relate to .PLIST.startup? Can we use this to get around
explictely listing the RC-files?
