Thanks Joost for posting in the dev list and for explaining your proposed 
approach there.  I've just read your thread in the dev list:

http://thread.gmane.org/gmane.linux.gentoo.devel/72969


Zac's response helped me understand better what the Gentoo devs have been 
suggesting here:

http://archives.gentoo.org/gentoo-dev/msg_020fa80d72c84c5b587b90d8001264ef.xml

and it does make sense - their version of initramfs-'lite'.

From what I understand:

1.  The minimal initramfs will only need to be built once (and rarely rebuilt 
thereafter).  This removes one of my fears and it was a main objection for me 
- I would hate to have to rebuild initramfs every time I roll a new kernel, or 
libs and what not of fs happen to be udpated, etc.

2. If initramfs fails, then Zac says it will drop you into a minimal shell, so 
we should still be able to recover/troubleshoot/reboot from there.

The only drawback is the 2 minutes it will take a user the first time this 
change is introduced to build the initramfs and change the kernel line in 
grub.conf.  I am warming up to this proposal because it seems to me that it 
will end up being less painful that I originally thought.

However, I still see it as a workaround to a more elegant solution, which as 
Joost and others suggest would involve separating udev's probing for devices 
with the rules running of scripts for them.
