Hello,

What the ???? Says he incredulously. Howinhell am I supposed to be able to
use 2 sound cards, in the reverse order from discovery?

I normally assign the mobo audio to private use, like skype, and have an
Audigy2 Value (SB0400) card that does all the main audio here. To do that,
here is my F8 modprobe.conf:

alias scsi_hostadapter libata
alias scsi_hostadapter1 sata_sil
alias scsi_hostadapter2 pata_amd
--------
Humm, I could reverse that and put my drives back in the same order as they
were before... But that wouldn't fix grub. :( LABEL's make it work anyway.

The audio stuff:
--------
alias snd-card-0 snd-emu10k1
alias snd-card-1 snd-hda-intel
options snd-hda-intel index=1
options snd-emu10k1 index=0
options snd-intel8x0 index=2
options snd-mpu401 index=3

alias eth0 forcedeth

How am I to effect this same setup for F10 when it is out? That would be a
total show stopper for me if I cannot.

How does one go about disabling that?

It's not easy. The Linux kernel automatically assigns a link-local IPv6
address to any interface that's brought up. If you don't want to use
IPv6 at all, you can use /etc/modprobe.conf to prevent the appropriate
module from being loaded. (ISTR that it used to be called net-pf-10,
but that module doesn't seem to exist anymore; I'd try disabling the
ipv6 module.)

To get rid of the IPv6 address on a particular interface, you should be
able to use some variation of 'ip addr ...'.

The only way I know of to prevent the kernel from assigning an address
when an interface is brought up is to set the MTU to a ridiculously low
value before bringing the interface up. If the MTU is too low for IPv6
to work, the kernel won't assign the address. Once the interface is up,
you can set the MTU back to what you want and assign an IPv4 address (if
desired). Needless to say, this is an ugly hack, and it's not supported
by the networking scripts.
