Default very common kernel modules slow down the boot process

This *should* be in the background and not actually be delaying the boot.

The point is: Why is it started anyway? I have *no* wireless! No need to eat disk/CPU resources (which *is*
delaying the boot).

Authentication isn't just for wireless anymore... Many network
switches can be configured to require 802.1x authentication from a
system before allowing access to the network. I'll be looking into
enabling 802.1x authentication here at work this summer. This is a
case of having things "just work" - having the world's fastest boot
time shouldn't be the ultimate goal here.

the hell you say! My LFS install sitting on my 8 meg flash card boots wicked fast and 'just works'.

If by 'just works' you mean brings me to a single user mode shell prompt with just enough support to mount a ro ext2 filesystem and startup my eth0 hardware with no other network hardware support, with only just enough commands available to create iptable rules on the cmdline with no editor on the system.

Ah, OK. Still a bug with USB drivers, though.

What's your bug #?

NM has support for wired 802.1x authentication via wpa_supplicant.
While there isn't UI for it quite yet, we'll be adding that UI in over
the next week or so. If the right things are set in GConf it'll work.

Now getting this working for system connections is slightly more work,
because we're blocking on adding the necessary keys to ifcfg files. I
simply need to sit down and work through what needs to get added to
ifcfg files, and then NM will grow system WPA and wired 802.1x
connections quite easily.
