compile kernel once for multiple distros?

rgiggs · 06-02-2004, 06:36 PM

hi,
suppose i install 2 different distros on 2 different partitions. then i compiled a kernel while running the distro 1. now, i also want to use the same kernel with distro 2.
can i simply copy over the /usr/src/<version> and /lib/modules/<version> from distro 1 to distro 2 partition? would that have the same effect as if i also compiled the kernel while running distro 2? then just copy bzImage to /boot and modify bootloader accordingly.
in short, is it possible to compile a kernel only once to use with multiple distros? if so, did i do enough as i said above or do i need to do something else?
thanks.

I have never tried this, but I think what you are saying can be done.

It can be done. Check out www.linuxfromscratch.org for documentation on the details.
