I couldn't agree more... One of the things in Solaris that was always a pain.
Just write a monitoring script that enumerates all devices... On linux you
simply write a loop, start with eth0 and go up. On Solaris, you parse
path_to_inst, then go from there iterating over the devices and instances...
Not real hard to do but makes a script go from 80 lines on Linux to about 250
lines on Solaris.
Oh and then of course there is the lovely implementation in Oracle RAC (and
many other clustered pieces of software) that wants the same interface name on
all hosts. Good luck finding two identical systems for the demo tomorrow
Essentially, having names per driver sounds good - until you actually lived
it. Then you realize you gain virtually nothing (how often have you really
looked at the cabeling of a server after its initial install) and made it
significanly more complex to script and maintain.
Censorship: noun, circa 1591. a: Relief of the burden of independent thinking.
