well, i assume you can always force a re-generation by the tool, but by
default you would use the networking tool config that your installation
prefers ... i could be totally off track here, you really have to ask
the developers :)

heh, sorry ... reflexes of an old ubuntu developer ... if someone says 
NIH i go into defensive mode and expect you refer to ubuntu development

well, there seemingly are problems if you run linux on a virtual switch
with dynamically generated interfaces or special servers which use bios
names for devices or some such, i guess linux has grown into areas
where it had not been used before, it might not affect your desktop or
home server install but there might actually be usecases for it ...

this is like bringing support for 1024 partitions to the kernel, 90% of
linux users will never need such a feature, but it needs to be there
for ... well. supercomputing, big data mangement, massive cloud servers
or whatever.

(i find it super ugly as well, but i guess there were actual reasons to
invest worktime to implement it)
