## @(#) Startup a jail chroot environment -Keith Farrar <farrar@parc.xerox.com>
## @(#)  jailbait.parc.xerox.com:/usr/local/etc/rc.d/jail-script.sh
## Conventions:
## My jails have neither console nor network logins, so I feed the
##  shell argument of this script to manage jailed accounts and services.
## In normal usage, I create one instance of this script per jailed
##  service, named /usr/local/etc/rc.d/jail-${JAILIPPADDR}.sh
## Each jail file system is rooted at /local/jail/${JAILIPPADR}/
