1# Setup chroot jail for NeXT, NEXTSTEP3. 2# Some remarks to the NEXTSTEP3 jail apply: 3# syslog: 4# Logging with syslog(3) uses a sendto ("/dev/log"). For this to work in 5# the jail, ${POSTFIX_DIR}/dev/log must be a hard link to /dev/log. This 6# fails if /usr/spool/postfix is on another filesystem, and consequently, 7# running chrooted will not be possible, unless you like to run your mail 8# system without logging (not). 9# 10# For this trick to work, the following should be run at every reboot, 11# preferably from /etc/rc, after syslog has been started (and given time 12# to create /dev/log): 13# POSTFIX_DIR=/usr/spool/postfix 14# rm ${POSTFIX_DIR}/dev/log 15# ln /dev/log ${POSTFIX_DIR}/dev/log 16 17set -e 18 19umask 022 20 21POSTFIX_DIR=${POSTFIX_DIR-/usr/spool/postfix} 22 23cd ${POSTFIX_DIR} 24 25# If this fails, running chrooted will be useless. 26mkdir dev 27ln /dev/log dev 28 29mkdir etc etc/zoneinfo 30cp /etc/zoneinfo/localtime etc/zoneinfo 31cp /etc/resolv.conf etc 32
