dynamically adding init services from boot

[fariouche]

Hello,
I have a script that runs in sysinit runlevel that scans for available network interfaces (especially wlan) and create various configs, including the symlink in init.d
It then add the interfaces to the boot runlevel.

The reason is that I use the same binary installation (gentoo) on multiple hardwares, and I would like to avoid to create all the possible symlinks in /etc/init.d/net.* even if the interface does not exist.

My question is just to know if running "rc-update add boot net.wlan1", for example, from inside the sysinit runlevel will not trigger any side effects?
So far i do not see any problem, but maybe I will run into more subtle issues?

Thanks!

actually it does not work. for some reason, the service is added to the boot runlevel, but is not run when the boot runlevel is executed. (except if I reboot of course)
however, the script is property executed if it is a dependency of an other script that is already in the boot runlevel

a call to rc-update -u after the files are created and added seems to fix the issue

nice trick, would be great if we can have this trick write down in wiki or other docs.

if i get to implement #749, you'd be able to do depend() { need net.$iface } on a service, and that symlink would be made automatically
