Add possibility to run a command after configuration is applied

[gabri94]

In order to use OpenWISP with LibreMesh, we need a way to call the command "lime-config" after the configuration has been fetched, but before the networking get reloaded.

I propose to add a parameter to specify a generic command in the config file.

Question: does lime-config work with a single configuration file or multiple files?

Take a look at this script that is used internally by openwisp-config: openwisp-reload-config.

It's a modified version of OpenWRT's reload-config (procd), which also explicitly calls /etc/init.d/<service> reload if necessary.

That's a way of doing it which wouldn't need to do new development.

An alternative would be to add some kind of customisable hook to call when the configuration is applied, which would also be interesting.

Could you find the source code of lime-config and link it here? I want to take a look at it but can't find it quickly.

lime-config read a couple of config files and write almost everything else

@G10h4ck thanks for the info, could you add the link to the source code of lime-config please?

I guess the best thing is to add a generic hook to call lime-config as suggested by @gabri94. Stay tuned.
