Excellent!  Thank you very much Akemi.  I was browsing through the spec file 
and encountered all those sections that you wrote up in the wiki.  I did not 
wish to dig through all those details to figure out how to spec file works. 
Your recipe is exactly what I need!  Thanks!

A short followup:  You have a warning at the beginning of the wiki that it 
is almost not necessary to build a custom kernel.  My problem is that I need 
a kernel that's able to mount a squashfs fs on a loop device during boot-up. 
  The standard kernel has both squashfs and loop as .ko.  I believe I need 
them built-in.  If I'm wrong, please advise.

Thanks again!

Ken
