The reason is this: both /etc/rc.local and all things in /usr/local/etc/rc.d will be executed after the builtin logid for launching jails is executed. The problem here is that if you use the standard /etc/rc.conf means for launching jails, (take a look at /etc/defaults/rc.conf for an example), the jail commands will be executed first. The last thing /etc/rc does is invoke /etc/rc.local and all the /usr/local/etc/rc.d scripts. His problem is that he needs DNS up *before* the jail commands run. Here's a hackish way to do it that might work. 1. Move the /usr/local/etc/rc.d/svscan.sh script out of /usr/local/etc/rc.d. Maybe put it in /usr/local/etc. Just put it somewhere where it won't get executed automatically. 2. Put the following lines in /etc/rc.conf named_enable="YES" named_program="/usr/local/etc/svscan.sh" # (if this is where you put it) named_flags="start" unset named_chrootdir # defeat some built-in BIND-oriented logic unset named_chroot_autoupdate # ditto The logic built into /etc/rc launches DNS before jails. By hijacking the "named" flags and using them for DJB, you should be able to get DJB to launch at the appropriate time. Good luck. Paco
