The rt-kernel project is completely distro agnostic. It's your distro
that potentially makes any kernel distro specific. I don't know what
distros might do this for the rt-kernel, if any.

The rt-kernel project always patches the kernel.org kernel and even
though I run Gentoo I do not run Gentoo's kernels as I don't know what
they've added or why. I figure if it's important they'll post it back
to kernel.org and Linus will decide. There is absolutely no problem
running this kernel on a Gentoo box and I don't know of any problems
running it on any distro box. you just don't get any special stuff the
distro package thinks is important to add.

On Gentoo we have the pro-audio overlay which makes the
distro-agnostic rt-sources available. It's equivalent to me going to
the rt-sources site and grabbing all that stuff but easier. emerge
gentoo-sources or emerge rt-sources. Either way I do exactly the same
amount of work, but with rt-sources I get the vanilla kernel with rt
patches.

Hope this helps,
Mark
