Hi Chris,
eth1 will be bought up when the PCMCIA subsystem starts. Basically,
when the networking script is run from /etc/rcN.d/ it will do an 'ifup
-a' which will bring up any network devices marked 'auto'. A little
later the pcmcia subsystem will start, and if you have a ethernet card
in the PCMCIA slot, cardmgr and friends *should* (in a normal
installation) detect it, beep, look in /etc/network/interfaces, and
bring it up for you. If you don't have the card in there, it will come
up on insertion.
If you consider this ordering you should immediately realize why
adding 'auto' to eth1 screws things up. The networking script can't
bring it up because it is PCMCIA, the pcmcia script can't bring it up
because the 'ifup -a' from the network script marked the device as
failed (in /etc/network/ifstate). The user then needs to go in and do
a 'ifdown eth1' followed by a 'ifup eth1' or something at that point
to bring sanity to the interfaces.
This approach works just fine for me on two different laptops. I
do believe it is the "right thing" for Debian.....but you don't have
to take my word for it ;-)
Cheers!
