Of course you can. The kernel is, after all, just code. Somebody else mentioned cross compiling, which is probably not what you care about. Sure, compiling a PPC kernel on intel is probably going to be a major pain. But compiling a kernel for your 386 on your dual P-III (or vice versa, if you're masochistic) is just fine, and the binaries should be completely indistinguishable if you're using the same compilers and stuff. One thing that will make this easier for you is the Debian tool 'make-kpkg' in the kernel-package package. It allows you to make a .deb file out of your kernel. So if you want to compile a new kernel for your 386 on your P-III, just use make-kpkg to create a .deb out of it, copy it over to the 386 and use dpkg to install it. The kernel sources should be completely self-contained in their own source tree, so there's no reason you can't have /usr/src/linux-2.2.18 and linux-2.4.0 and linux-2.5.0 when it comes out. noah -- _______________________________________________________ | Web: http://web.morgul.net/~frodo/ | PGP Public Key: http://web.morgul.net/~frodo/mail.html
