# Setup chroot jail for NeXT, NEXTSTEP3. # Some remarks to the NEXTSTEP3 jail apply: # syslog: # Logging with syslog(3) uses a sendto ("/dev/log"). Forthis 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).
java.lang.NullPointerException # Forthis 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}
# Ifthis fails, running chrooted will be useless.
