# Setup chroot jail for NeXT, NEXTSTEP3.
# Some remarks to the NEXTSTEP3 jail apply:
# syslog:
# Logging with syslog(3) uses a sendto ("/dev/log"). For this to work in
# the jail, ${POSTFIX_DIR}/dev/log must be a hard link to /dev/log. This
# fails if /usr/spool/postfix is on another filesystem, and consequently,
# running chrooted will not be possible, unless you like to run your mail
# system without logging (not).
#
# For this trick to work, the following should be run at every reboot,
# preferably from /etc/rc, after syslog has been started (and given time
# to create /dev/log):
# POSTFIX_DIR=/usr/spool/postfix
# rm ${POSTFIX_DIR}/dev/log
# ln /dev/log ${POSTFIX_DIR}/dev/log
set -e
umask 022
POSTFIX_DIR=${POSTFIX_DIR-/usr/spool/postfix}
cd ${POSTFIX_DIR}
# If this fails, running chrooted will be useless.
