# BIND named process options
# ~~~~~~~~~~~~~~~~~~~~~~~~~~
# Currently, you can use the following options:
#
# ROOTDIR="/some/where" -- will run named in a chroot environment.
# you must set up the chroot environment
# (install the bind-chroot package) before
# doing this.
#
# OPTIONS="whatever" -- These additional options will be passed to named
# at startup. Don't add -t here, use ROOTDIR instead.
#
# ENABLE_ZONE_WRITE=yes -- If SELinux is disabled, then allow named to write
# its zone files and create files in its $ROOTDIR/var/named
# directory, necessary for DDNS and slave zone transfers.
# Slave zones should reside in the $ROOTDIR/var/named/slaves
# directory, in which case you would not need to enable zone
# writes. If SELinux is enabled, you must use only the
# 'named_write_master_zones' variable to enable zone writes.
#
# ENABLE_SDB=yes -- This enables use of 'named_sdb', which has support
# -- for the ldap, pgsql and dir zone database backends
# -- compiled in, to be used instead of named.
ROOTDIR=/var/named/chroot |
