The exact sequence was: Step 1: freebsd-update from 9.1 to 9.2 Step 2: make buildworld Step 3: make build_kernel KERNCONF=LAFN Step 4: make install_kernel KERNCONF=LAFN Step 5: reboot Step 6: mergemaster -p Step 7: make installworld Step 8: mergemaster -i Step 9: make delete-old Step 10: reboot oops, something went wrong.. After step 5, uname -a still showed 9.2 but now it listed the kernel I built rather than generic. _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
