Whee!  Much rejoice :-).

Please enlighten me.  Why is that bad?

Just diffed my linuxrc against Gerte's, he does the same thing.
Which reminds me, I get a message on every boot up saying that
"reiserfs assumes mounted read-only, skipping journal playback".  I

(I also get "attempt to access beyond end of device" and
"ichxrom_init_one(): Unable to register resource 0xffb00000-0xffffffff
- kernel bug?", but that's a whole other discussion.  Humn =)).

Good question.  No idea how udev works :-(.

We should form a support group for other unfortunates!
(We could use it as an excuse for drinking if nothing else.)

Neat!  Except for...

This one.  Won't work for eg. reiserfs users (me).
(Think I'll be reinstalling with ext2 anyway, to get noflushd working,
but anyhow.)
