I was wondering if it is possible to separate the configuration from /etc/network/interfaces file into separate files, like one stanza in one file and another stanza in another file? (similar to CentOS). Or from /etc/network/interfaces file is it possible to call other interfaces files? My idea is to have ethernet stanzas in one file, vlan's in another, vpn's in another, etc (or something similar). By doing it this way, it would be easier for me to edit and parse (yes I know there are parsers out there), but I think by having them separate in different files it would be more organized.
I have tried to look for answers in google for several days, and man interfaces but I haven't found anything. I'm thinking is not possible (unless modifying source code from the OS I guess). Anyone knows anything about this?
I'm using Ubuntu 12.04 LTS Server x64
