1 1. Track -STABLE: cd /usr/src && cvsup stable-supfile 2 3 2. Read and understand /usr/src/UPDATING. 4 5 3. Run mergemaster; this should be done by experienced 6 personnel only. 7 8 4. If mergemaster did not update /dev, run 9 10 cd /dev && sh MAKDEV all 11 12 5. Ensure that /etc/make.conf does not build unnecessary stuff 13 (such as Fortran, Objective C, sendmail, profiling libraries) 14 15 6. Verify that fsck_y_enable="YES" is defined in /etc/rc.conf. 16 Otherwise, fsck might wait for console input and halt the 17 boot process. 18 19 7. Verify that the kernel config file is up to date and that 20 no new requirements were added which have not been met 21 yet (refer to UPDATING). 22 23 Constraints: 24 25 pair1, 11, 12: SMP/APIC_IO can be set; firewall optional. 26 pair2: SMP/APIC_IO MUST NOT be set; firewall MUST be set. 27 28 Ensure that SMP and APIC_IO are only set, if the machine has 29 multiple processors. A SMP kernel will not boot on an UP 30 machine. "sysctl hw.ncpu" will tell you the number of CPUs. 31 32 8. Clean up: 33 34 rm -rf /usr/obj 35 36 9. nohup make buildworld -jX & 37 38 where X is <number of cpus + 1> 39 40 10. make buildkernel installkernel KERNCONF=NEWPB1 41 42 Adapt kernel config name as necessary. 43 44 11. Take a snapshot of the running processes/services: 45 46 ps ax > /root/pslist-old 47 48 12. Reboot. 49 50 13. make installworld 51 52 14. Reboot. 53 54 15. Compare the current process list with the saved one. Ensure 55 that all services which ran before are running now. 56
