We should probably come up with a published list of things (worst case) that need to be rebuit when upgrading a kernel. People can usually get by with simply recompiling/relinking the kernel, and are suprised when that doesn't work correctly. I am usually prepared to (not necessarily in this order): compile, relink and install libkvm. compile, relink and install ps, w, and other utilities dependent on libkvm. compile, relink and install config. compile, relink and install the /usr/src/lkm's. When doing lots of kernel development, I don't use any LKM's so that I don't run into troubles because of those. Even dealing with the items above, there is still the (not-so-often) possibility of other trouble when upgrading a kernel (esp. a -current kernel.) -- John dyson@freebsd.org jdyson@nc.com
