2.6.20 zImage.prep??

2.6.20 zImage.prep??

[Bob Brose]

Is PReP currently suported? The last kernel version I could make a
zImage.prep in was 2.6.14. I see some references to PReP and new
kernels here but nothing I'd call definitive.

>From digging around the net it looks like one is supposed to use
mkvmlinuz to do this now however:

1) The utilities mkprep, mktree and mkbugboot aren't build be default
in 2.6.20 from what I can see and

2) Even when I build them and try mkvmlinuz there are errors:
debian:/usr/src/linux# mkvmlinuz -v -o vmlinuz.prep -a prep -k vmlinux -r 2.4.20

Sorry, I do not know how to handle PowerPC sub-architecture prep in version 2.4.20.

This is debian sid. If I try the mkvmlinuz command for chrp it works fine.

I can only tell you that it works for 2.6.18 using the debian linux 
image package. But you need to install linux-image-2.6.18-prep instead 
of linux-image-2.6.18-powerpc.
