pre-up is used for other purposes as well, I've written quit some extensions
to Debian's ifupdown. WIFI-configuration takes place at that time.

Your point assumes that the work done by LXC covers all cases of use; however,
this is probably not the case - actually, the lack of decent veth
configurability is my intention for this patch. Having an extra hook available,
even if not used, will make it easier for admins to adapt their setup to their
needs - and not having to re-learn C programming like I did in the last few
days :-)
