Complementing the above init script is a configuration file

/etc/default/bind

, which con 

tains configurable parameters used by the script. This would be created by the

postinst

script if it was not already present, and removed on purge by the

postrm

script.

# Specified parameters to pass to named. See named(8).

# You may uncomment the following line, and edit to taste.

#PARAMS=" u nobody"

Another example on which you can base your

/etc/init.d

scripts is found in

/etc/init.d

/skeleton

.

If this package is happy with the default setup from

update rc.d

, namely an ordering num 

ber of 20 and having named running in all runlevels, it can say in its

postinst

:

update rc.d bind defaults >/dev/null

And in its

postrm

, to remove the links when the package is purged:

if [ "$1" = purge ]; then

update rc.d bind remove >/dev/null
