Unable to eject boot cd during kickstart install

[dwight at supercomputer.org]

It sounds like there's some process left around which is keeping the 
device open. That would be the first thing I'd check. If nothing is 
obvious from a ps(1), then you'll have to dig deeper.

lsof(1) and/or an `fuser -v` are typically used to track this down. 
The trouble is that these aren't available from the F2 virtual 
terminal. I'm going from memory at the moment, but I'm pretty 
certain this is the case.

To use these utilities, you'll have to do something like the 
following:
   1. chroot /mnt/system
   2. mount  up /sys (Check fstab, it would be something like 
mount -t sysfs /sys
   3. mount up /proc 
   4. /sbin/start_udev

You should then be able to use lsof and/or fuser.

You can also now do all sorts of other nifty things.

Note that to exit this environment cleanly, you have to clean up in 
the reverse order. Starting will killing the udevd daemon. 

Hope that helps.
