 Posted: Fri Jan 14, 2011 12:35 am Post subject: [SOLVED] The depend() function in init.d scripts |
 |
|
I'm trying to set up multiple lircd devices in a relatively straightforward and manageable manner. I'm using lirc's listen/connect to pass traffic from all of the lircd.XXX daemons up to the master lircd
| Code: | morocco ~ # ls -l /etc/init.d/lircd*
-rwxr-xr-x 1 root root 1094 Jan 13 18:52 /etc/init.d/lircd
lrwxrwxrwx 1 root root 5 Jan 6 00:30 /etc/init.d/lircd.udp -> lircd
morocco ~ # cat /etc/conf.d/lircd
LIRCD_OPTS="--device=/dev/lirc0 --driver=default --connect=localhost:8765"
RC_NEED="lircd.udp"
morocco ~ # cat /etc/conf.d/lircd.udp
LIRCD_OPTS="--device=5000 --driver=udp --listen=127.0.0.1:8765" |
I also edited /etc/init.d/lircd to make the socket unique to each instance
| Code: | | morocco ~ # cat /etc/init.d/lircd |
| Code: | PIDFILE=/var/run/lirc/${SVCNAME}.pid
LIRCD_SYMLINKFILE=/dev/${SVCNAME}
LIRCD_SOCKET=/var/run/lirc/${SVCNAME} |
| Code: | depend() {
need localmount
use modules
[[ ${SVCNAME} -eq 'lircd' ]] && provide lirc
} |
| Code: | start-stop-daemon --start --quiet --pidfile "${PIDFILE}" --exec /usr/sbin/lircd -- \
-P "${PIDFILE}" -o "${LIRCD_SOCKET}" ${LIRCD_OPTS} |
Basically it works 
| Code: | morocco ~ # /etc/init.d/lircd start
* Service lircd starting
* Service lircd.udp starting
* Service lircd.udp started
* Service lircd started
|
However, when the depcache is regenerated, I get this error:
| Code: | morocco ~ # touch /etc/init.d/lircd && /etc/init.d/lircd start
* Caching service dependencies ...
/var/lib/init.d/depcache: line 1819: [[: lircd.udp: syntax error: invalid arithmetic operator (error token is ".udp")
* Service lircd starting
* Service lircd.udp starting
* Service lircd.udp started
* Service lircd started |
The relevant bit from the depcache:
| Code: | morocco ~ # grep -n lircd.udp -A39 /var/lib/init.d/depcache
1791:#*** /etc/init.d/lircd.udp ***
1792-
1793:SVCNAME="/etc/init.d/lircd.udp"
1794-SVCNAME="${SVCNAME##*/}"
1795-myservice="${SVCNAME}"
1796-echo "RCSCRIPT ${SVCNAME}"
1797-
1798-echo "MTIME 1294291835"
1799-
1800-(
1801- # Get settings for rc-script ...
1802-
1803- [ -e /etc/conf.d/net ] && \
1804- [ "${SVCNAME%%.*}" = "net" ] && \
1805- [ "${SVCNAME#*.}" != "${SVCNAME}" ] && source /etc/conf.d/net
1806-
1807- [ -e "/etc/conf.d/${SVCNAME}" ] && source "/etc/conf.d/${SVCNAME}"
1808-
1809- [ -e /etc/rc.conf ] && source /etc/rc.conf
1810-
1811- depend() {
1812- return 0
1813- }
1814-
1815- # Actual depend() function ...
1816- depend() {
1817- need localmount
1818- use modules
1819- [[ ${SVCNAME} -eq 'lircd' ]] && provide lirc
1820- return 0
1821- }
1822-
1823- depend
1824-
1825- for x in ${RC_NEED} ; do
1826- need "${x}"
1827- done
1828-
1829- for x in ${RC_USE} ; do
1830- use "${x}"
1831- done
1832-) |
My question is, what is depcache error all about? As far as I can tell, this method is working quite well, but apparently I'm Doing It Wrong. What is the preferred way to accomplish this?

| Remove the bash-isms and do what the rest of the rc code does - "[ ${SVCNAME} = "lircd" ]" |
