First of all:
The observed behavior is (unfortunately) not dependent on udev-111 <->
udev-110. We have seen this behavior more often, lately, still trying to
live without persistent, auto-generated network rules.
Maybe we'll have to refrain from that, but still udev's naming behavior
puzzles me a bit:
We have card a -> eth0 (custom rule via PCI-id)
card b -> eth1 (should become that automatically,
pcmcia-slotted)
In the normal boot process (over 50% of the time... *sigh* ..), card a
is found first and becomes eth0 straight away-> no problem; card b gets
found second and becomes eth1.
Problems arise when card b is found first, because:
card b becomes eth0
our custom rule wants to assign card a -> eth0
card b gets moved out of the way; because card a is still eth1, card b
becomes eth1_rename.
card a becomes eth0; but card b stays eth1_rename
Shouldn't the final step (eth1_rename -> eth1) be done somehow by
something? Is this indeed expected behavior?
greets,
Jens
