if [ x${_RC_CONF} !=3D x1 ]; then . /etc/rc.conf; fi
in the beginning of the local startup script?
if it really requires it, it could plainly source it in the beginning,
or selectively using the above if statement when /etc/defaults/rc.conf
would do _RC_CONF=3D1; export _RC_CONF
that's not a very good idea, but it would - at least - fix the behaviour
to be the right way. please read on...
what i dislike most of the complex local invocation method described in
the mail referred, is the amount of subprocesses spawned by backticks. i
see that there are not many people on very small or even embedded
systems but a lot of subprocesses tend to be a real pain in the ass on
slow boxes. imagine a local_startup dir with let's say 10 .sh files.
with basename, echo in a backticked subshell and dd invocations you will
catch execution overhead of 30(!) processes you do not really need.
i think that this is a specific thing about freebsd, being able to run
on really pathologic (speak: badly outdated) hardware and start up into
multiuser mode in under 30 seconds.
try it... start up an out of the box redhat linux on a pentium-60 with
32mb ram. although this box is capable of being a very efficient isdn
router/firewall/application proxy, it won't start up very fast (eg. over
2 minutes for a reboot)
sorry danny, these are just my EUR0.02
