[gentoo-dev] writing net.xx style init script

[paul kölle]

Hi all,

I need to write an init-script for multiple instances of the same
service with different configurations (need to start/stop them
individually) similar to what the net.xx scripts do.

I thought I could get the instance name from $0 and use it as a key to
look up the configuration in /etc/conf.d/servicename but $0 is always
/sbin/runscript.sh. The net.xx scripts know the name as ${IFACE} in
start() without doing something obvious... How do I get the name of the
called script in /etc/init.d? Better ideas?

thanks
 Paul

Take a look at the sshd init script.

use $SVCNAME

see the sshd init.d script for some examples

thanks mike, you got me started ;)

actually there is plenty of choice here:

gentoo ~ # cat /etc/init.d/dummy
#!/sbin/runscript


start() {
        einfo "$(set)"
}

leads to:
gentoo ~ # ls -l /etc/init.d/
.
-rwxr-x---  1 root  root    267 Aug 20 17:10 dummy2
lrwxrwxrwx  1 root  root     18 Aug 20 17:12 dummy2.v1 -> /etc/init.d/dummy2
.

gentoo ~ # /etc/init.d/dummy2.v1 start
 * rc_name is: dummy2.v1
 * myservice is: dummy2.v1
 * myscript is: /etc/init.d/dummy2.v1
 * SVCNAME is: dummy2.v1
 * BASH_ARGV[1]: /etc/init.d/dummy2.v1
 * BASH_SOURCE[0]: /etc/init.d/dummy2.v1

I'll stick with SVCNAME for now ;)

thanks again,
 Paul

no, there isnt ... SVCNAME is the only one the base-layout team guarantees we 
wont change ... if we can figure out a way to break the others, we will ;)

Sounds like you want to look at the openvpn or vsftpd init scripts as they 
allow multiplexing, which I think is what you are after.
