orogenconf will fail if a component interface is now incompatible with an existing configuration file

[doudou]

It seems that orogenconf actually loads the configuration files, which makes it fail if a component's
configuration file is invalid because the interface changed). This is obviously a critical use-case
(one will want to geneate a new config file).

It might apply only to the config file(s) for the orogenconf's argument. I only tried this one.

I have encountered similar problems. How did you finally solve them?

[doudou]

By fixing the configuration file. Behavior should be improved during orogenconf, to simply ignore the invalid conf file (or, better, by loading none of the Syskit configuration, which are not needed during code generation)
