I decided I wanted a 64bit kernel for my UK2 server (seeing as it's an Athlon X2, and I wanted an ubuntu amd64 chroot to work on it).
After a little playing around, this is how you do it:
- Get your kernel
- Extract it
make menuconfig ARCH=x86_64
- Create some
linux-amd64-ld, etc. wrappers. Some need
-m64options. Others autodetect what's required. (I made a tarball of my wrappers, but they've been lost.)
CONCURRENCY_LEVEL=4 make-kpkg --append-to-version '-londonpride' --revision '1.00' --rootcmd fakeroot --arch amd64 kernel_image
- Extract the control.tar.gz from the deb, edit control file, and change the architecture to i386.
Unfortunaly, in the week after this, my machine died of disk corruption. This is the 2nd time it's happened. I hope UK2 don't use dodgy hardware...
