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.
