DOC vs. IDE

you can't fit X onto the DoC you can buy today.

Fasted boot I've seen is with the kernel in DoC, then mount /dev/hda1 as
/.

Even an X like Qt embedded?  My Zaurus only has 32Mb on it, and it boots 
into X in about 4 seconds.  While I don't expect _that_ speedy of a 
boot, I would think I could achieve significantly less than 35(ish) 
seconds it takes now.  Also, did you factor in the IDE spinup boot delay 
of having an IDE  /.  directory?  If the DOC+IDE is faster, do you mean 
throughput wise or time wise?  I'm referring to an earlier message that 
you replied to Todd Johnson and his boot times (message below).  It 
seemed as if the 2 emails conflict in what they're saying, so I just 
wanted to ask for a little clarification (not doubting you, just a 
little unclear on the principle).

Essentially what I'm wondering is if a small footprint X could be booted 
into via DOC and if it would be faster than DOC+IDE (considering the IDE 
spinup delay).  

Your thoughts?

you can't do anything until the HDD spins up, and yes it's because you've
god file system on the HDD. There's not much to be done for this.
