The addition of *_enable variables can be easily done with RC_NG, and a few
minor changes to the existing rc.d scripts. I have already converted my
ports to use a combination of the old rc.d and the new RC_NG system:
Port Script *_enable
security/cyrus-sasl cyrus_pwcheck.sh both
saslauthd1.sh both
www/apache13-fp apache.sh RC_NG only
NOTE: The apache.sh script does work on <5.x, but it doesn't support the
apache_enable variable in the non-RC_NG case.
The thing is that the combined RC_NG/pre-RC_NG rc.d script has to be
designed to run under FreeBSD 5.x+ (with rc.subr) and FreeBSD < 5.x
(without rc.subr) as follows:
if [ -f /etc/rc.subr ] ; then
# RC_NG rc.d script
. /etc/rc.subr
:
- Rcng style rc.d script
else
# pre-RC_NG rc.d scipt
source rc.conf files (${prefix}/etc/rc.conf.d/scriptname, /etc/rc.conf,
/etc/rc.conf.d/scriptname)
case "$scriptname_enable"
[Yy][Ee][Ss])
old script for pre rcng systems
;;
*)
rc=0
;;
esac
exit $rc
fi
RC_NG needs a new function added to rc.subr (load_local_rc_config), this
function loads the rc.conf style files as shown above. For this function see
PR 44800:
http://www.freebsd.org/cgi/query-pr.cgi?pr=conf/44800
This PR also has links to other PRs where I had converted several ports
scripts to a combined RC_NG/pre-RC_NG rc.d script.
