We aren't trying to come up with new rocks to carry; we sent the proposal Peter and I discussed to netdev to have char devices; we got shot down, and GregKH suggested this installer-based approach... Installer guys hate it. Repeat. :-(

Please don't send mails like this to anaconda-devel-list and netdev at
the same time. The lists serve two completely unrelated purposes.

1) make kickstart accept various different names by using libnetdevname or
2) make libnetdevname capable of telling us a reasonable name for an interface
for user display (i.e. smbios name with spaces instead of _ or somesuch)
3) display and log those names (and /possibly/ the real interface name) where
appropriate, which might include something like a "details" section describing
a particular interface.

What ever happened to the plan of making OS tools (i.e. anaconda,
NetworkManager, and ifup, but not necessarily ifconfig) use libnetdevname
to do this translation, and leaving the kernel names like they've always
been, which people are used to and people who aren't effected by won't
have to deal with, and having libnetdevname do the entire translation itself
in userland? This is what mdomsch and I discussed on Oct 30th.
I'm getting tired of the cycle of:
1) dell comes up with a suggestion
2) people don't like the way they're doing it
3) dell goes away and talks amongst themselves
4) dell comes up with a suggestion that ignores the feedback
5) goto step 2.

Renaming the devices is exactly what we were trying to get around by making
userland tools use libnetdevname.

You mean the kernel name here, not the "OS" name. And in general, changing
the kernel names isn't something we want. That's why we went down the whole
aliasing route in the first place!
