That's good news robb, after reading the post and article you referred to, the thing that bothers me is the "interfaces" file that could be overwritten any moment by Zentyal.
It has been said that a "post config hook" would do the trick, but I haven't got a clue how to make such a hook.
I also read bonding is a feature that could be included in 2.3 release...If I'm not mistaken the odd release will be a beta version...So if anything, for the final Zentyal version with bonding included we would have to wait for September?
I would really like to see someone explaining how to make a post config hook, or is creating a "/etc/ebox/hooks/network.postsetconf" file sufficient, as Javi posted?
Cheers.
