--aXNiKu4lnbRqA5kZ Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable 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=20 cron_enable=3D"YES" # Run the periodic job daemon. cron_program=3D"/usr/sbin/cron" # Which cron executable to run (if enable= d). cron_dst=3D"YES" # Handle DST transitions intelligently (YES/NO) cron_flags=3D"" # Which options to pass to the cron daemon. entropy_dir=3D"/var/db/entropy" # Set to NO to disable caching entropy via = cron. d134(8.3-S)[3]=20 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]=20 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=20 # $FreeBSD: head/etc/rc.d/cron 230099 2012-01-14 02:18:41Z dougb $ d134(8.3-S)[8]=20 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@. Thanks!
