Hi all,
Is it possible to use the fc15 kernel on fc14, and if so, how would you go about doing that?
I could of course just download the SRPM and recompile it, but I'd like to be able to easily update the system as well. I don't doubt other RPMs will be required, but I can't upgrade this system just yet, but still want to benefit from the much later kernel.
Are there too many dependency changes, such as module-init-tools, grub, initscripts, etc, that woud normally be tied to the kernel version to upgrade to the new one?
Thanks, Alex

Yes as of right now you can use it - however since the compiler and libraries changed in F15 you will/may have problems with some kernel modules - notably virtualbox.
I'd recommend getting the source rpm and building it on your f14 machine to avoid that issue.

I'm using the one from koji, works fine.

Do a test yum update $ yum --releasever=15 yum update see what it needs. You can always say n

You might want to limit that to:
yum --releasever=15 update kern* perf*
If all is good in the world that should pull in a newer compile toolchain + libs. If you're ok with that ... should be backward compatible ... this is perhaps a simpler to perform alternative to compiling the kernel yourself ... and probably easier to keep up to date too ..

kernels are generally stand alone and don't depend on other packages, so you can probably just download and install the f15 kernel directly (though if you are using RPM, make sure you use rpm -i and not -U or -F ie. install rather than update or freshen which will both remove the existing kernels). You might possibly have problems with things like X if the drivers depend too closely on the kernel version, so it is always worth making sure you can resort to a known good kernel if necessary, but I expect it will just work.

Largely yes but kernel modules require some caution:
a) The newer compiler will make some compile time kernel modules (such as virtualbox) not work unless you update the compiler on your f14 system to match the one used to compile the kernel (or recompile the kernel)
b) compiling nvidia kernel module - may have additional problema as the kernel headers changed and it may be missing linux_smp.h or something (forget the exact name).
So yes .. you are largely but not 100% correct :-)

In the past, I have seen an intimate relationship between the compiler version and the kernel. This was the case when I used to run FreeBSD. I would try to compile a most current release with a previous release compiler. I would either get compilation or link-load errors, or the kernel would not boot until I compiled it with the same compiler version that the released kernel was compiled with. Perhaps other individuals might recall the very early version of Linux.
