This is appreciated. It's something to add to my bag of tricks. Still, 
this punctuates the point. Why do we need so many workarounds? Because 
the kernel's behavior is stupid.

What I want -- aside from non-stupid behavior -- is a workalike for the 
Solaris ifconfig plumb and unplumb commands, something that sticks in 
the kernel configuration for the node. "ifconfig ethX unplumb" and it's 
gone, invisible, unavailable, forever not there until I "ifconfig ethX 
plumb" to reactivate it.

This only works if you have different RAID controllers. If you have 
identical controllers or many disks on a single JBOD interface then 
there is no way to control the enumeration order. You have to fall back 
on hacks like volume labels and UUIDs.
