rc.d/cron appears to ignore rcvar "cron_program" -- intentional?

[David Wolfskill]

I was poking around to see if I could find a reasonable way to set the
UNAME_r environment variable for an instance of cron(8) running in a
jail (so that cron-initiated tasks could automagically inherit the
value, without requiring that every crontab instance within the
jail specify it), and I started to think about ways to coerce the
cron_program variable from /etc/defaults/rc.conf:

d134(8.3-S)[2] grep cron defaults/rc.conf 
cron_enable="YES"       # Run the periodic job daemon.
cron_program="/usr/sbin/cron"   # Which cron executable to run (if enabled).
cron_dst="YES"          # Handle DST transitions intelligently (YES/NO)
cron_flags=""           # Which options to pass to the cron daemon.
entropy_dir="/var/db/entropy" # Set to NO to disable caching entropy via cron.
d134(8.3-S)[3] 

to set the environment variable.

But inspection of rc.d/cron shows:

d134(8.3-S)[6] grep cron_program rc.d/cron ; echo $?
1
d134(8.3-S)[7] 

Note: while the machine was running stable/8, I was looking at
files on the "head" slice:

d134(8.3-S)[7] grep '\$FreeBSD' rc.d/cron 
# $FreeBSD: head/etc/rc.d/cron 230099 2012-01-14 02:18:41Z dougb $
d134(8.3-S)[8] 

Does the observation make sense?

(If anyone has insights on how I might address the issue that catalyzed
my poking around, I'd be happy to receive them.)

Please Cc: me on responses, as I am not currently subscribed to rc at .

Thanks!

Peace,
david
