Hi,
While trying to get my script within the /etc/rc.d tree operational I
ran into some strange behaviour.
I intended to start a vncserver as part of the boot process. I build the
script based on several existing scripts (a.o. the apache script). The
script works as expected when run from the command line in a operational
FreeBSD system. During boot however it does not.
Probem description:
To be more specific it looks like the construction with the default
value of a variable defined in the script and possibly being overridden
in rc.conf DOES NOT WORK WHILE BOOTING.
Note that since this is my first rc.d script, I might as well be doing
something wrong, nevertheless the operation of the script works
different in the two modes.
Remark: I realize that there is a separate mailing list for rc.d things.
The website for it however does not show any messages (but then maybe
there are none). For this reason I post this message to both the general
questions and the rc mailing list.
Some details:

I recently installed this system from the 5.3 ISO. As far as I know
nothing was changed to the rc.d part.
