i think the real win won't necessarily be declaring a fast path
for known hw, but _remembering_ a fast path for _any_ hardware. 
i.e., if you've booted 10 times and never found ipv6, and always
found the same 3 filesystems in the same partitions, maybe it's
time to stop expecting anything else.  does udev remember anything
from boot to boot?  seems like it should if it doesn't.

but as you say, there are also a lot of simple cases:  most machines
have just one network interface, and it runs dhcp -- so once that
seems to be true, don't check for anything else.  most machines
have one fixed disk, etc.
