Compiling a New Kernel
Being one of these difficult people who like sticking to the old way of doing things, im still compiling my kernel the old way (config KERNELNAME; cd ../../KERNELNAME; make depend; make ; make install) :P I picked up a rumour on the mailing lists that this may no longer work in future/recent releases?

It's fine when you're rebuilding your kernel with the same sources as your installed world, but if you upgrade your sources and want to build the kernel then this method WILL NOT WORK in all cases (and there have been cases in the past when it would not work). This is why 'make buildkernel' and friends were introduced; they are guaranteed [1] to work properly in all cases. The exact steps are documented in the handbook.

Nowadays, the old way is only guarranteed to work if you've previously built and installed world, kernel with that same set of sources. The new way, 'make buildkernel' doesn't have that restriction, as it uses the compiler toolchain and so forth freshly created in the build area.

So any kernel built with this system will attempt to use the existing tools. If something critical to building the kernel, say the .mk files or compiler, have been updated and the kernel Makefile has been modified to work with the new .mk files, any attempt to build the kernel with existing, installed tools is doomed to failure. This is exactly correct. Examples in the past have included binutils/compiler upgrades and *.mk changes. Kris msg50727/pgp0.pgp Description: PGP signature

| By Jamie Heckford [EMAIL PROTECTED] | [ 2002-10-11 11:13 +0200 ] Bizarre how could it be different/not work if you have cvsup'd all of your sources including sys/ tree at exactly the same time, and compile your kernel just after the installworld? Ideally you should build, install, and boot your new kernel before installing your new world. If your new kernel fails to boot for whatever reason, you can easily boot the old kernel and have a fully functional system again. If you installworld before verifying your new kernel, you could run into worse problems if your new kernel doesn't load and you have to boot the old kernel with your new world.

The only problem that I have with this approach, is that I keep all of my source on a vinum raid-5 volume. If I reboot before doing a make installworld, then there is always the possibility that with the new kernel and the old world I may not be able to mount the volume. So I always shutdown but *not* reboot before doing the installworld.

The on-disk format has never changed, and though it's possible in the future, I'd hope it would do so in a compatible manner.
