Hi Sam

I recall about 7 years ago, give or take, when Sun released the new
T2000 line of servers, NICs changed from being eri0, hme0, qfe1and
similar to being e1000g0, e1000g1.....
You could grab the old NICs by using a regex. They were all of the
form aaaX (a=Alpha, X=Numeric)
"^[a-z][a-z][a-z][0-9]" or something like that.
It all happened inside the C code, so I plead ignorance of the details.

The new NIC IDs no longer fitted the regex, and it broke Hobbit. (Yes,
it was called Hobbit back then)
Henrik was pretty quick off the mark though, and sorted me out with a
patch within a day or three.
(I am guessing he wasn't so busy back then)

It is possible that you have encountered something similar.
Henrik? Could it be?

I would go to your sysadmin guys and get them to stop playing
silly-buggers with the NIC naming conventions.
If they refuse to be reasonable, you might have to petition Henrik for a fix.
I still owe Henrik a beer for that T2000 fix. :-)
