Hello All,

I am looking to use multiple kernel trees on the same distro. Example:-

2.6.19.1 for - software/tools development
2.4.34 for - embedded systems development.

I do know that 2.6 supports embedded in a big way....but still
requirement demands to work with such boards as an example:-

My question is HOW-TO enable a distro with multi kernel trees?
Presently am using Fedora Core 5/6 for much of the development
activities (Cell BE SDK related at Labs).

Any hints/suggestions would be a great leap for me to do this on my own.

this is really no big problem (as in: works OOTB), except that if you want to boot & run both kernels on the same (rootfs) installation, you will need to create wrappers around modutils and module-init-tools, as well as udev/devfs, or whichever device file system you prefer to use for each kernel. There are a few minor other details but none really shocking.

We've done this for "our" source distro, and it works just fine.

Cheers,

Auke
