Updating FreeBSD -CURRENT from source, and more

freebsd-from-source.md

Notes:

• the routine is personalised – things such as SDDM and graphics/drm-devel-kmod in the mix, and the longhand helps me to not make mistakes after being distracted (or falling asleep at the keyboard, or whatever)
• /bin/csh for all commands below, some no longer require root since I changed ownership of /usr/doc, /usr/obj, /usr/ports, and /usr/src.

Routine

1. glance at https://cgit.freebsd.org/src/log/, https://cgit.freebsd.org/src/tree/UPDATING#n29, and https://cgit.freebsd.org/ports/tree/UPDATING#n5 to estimate whether it's a good time to update
2. su -
3. pkg lock -l
4. pkg unlock emulators/virtualbox-ose-kmod graphics/drm-510-kmod graphics/drm-515-kmod
5. chown -vR grahamperrin /usr/obj/usr/src/amd64.amd64/sys/GENERIC-NODEBUG/usr/ports/
6. exit
7. git -C /usr/ports branch && git -C /usr/src branch
8. git -C /usr/ports pull --ff-only freebsd main && git -C /usr/src pull --ff-only freebsd main
9. repeat step 8 until no changes are found

echo "" ; date ; uname -sr ; echo "shell: $SHELL" ; echo "" ; set freebsdmaingitcommitcount="`git -C /usr/src rev-list --first-parent --count HEAD`" && echo "freebsd/main (FreeBSD-CURRENT) Git commit count: $freebsdmaingitcommitcount" && set freebsdmaingithash="`git -C /usr/src rev-list --max-count=1 HEAD`" && echo "freebsd/main Git hash: $freebsdmaingithash" && echo "<https://cgit.freebsd.org/src/commit/?id=$freebsdmaingithash>" && echo "– in context: <https://cgit.freebsd.org/src/log/?qt=range&q=$freebsdmaingithash>"

11. cd /usr/src && time make -j4 buildworld > & buildworld.log && time make DISABLE_VULNERABILITIES=yes -j2 buildkernel > & buildkernel.log && tail buildworld.log && tail buildkernel.log
12. continue using the desktop environment until completion of the builds
13. check the tails of the first and second logs for sanity
14. sudo bectl create n"$freebsdmaingitcommitcount"-"$freebsdmaingithash"-a && sudo bectl activate n"$freebsdmaingitcommitcount"-"$freebsdmaingithash"-a && sudo bectl mount n"$freebsdmaingitcommitcount"-"$freebsdmaingithash"-a /tmp/up
15. sudo sysrc -R /tmp/up sddm_enable="NO"
16. sudo bectl umount n"$freebsdmaingitcommitcount"-"$freebsdmaingithash"-a && bectl list -c creation
17. use bectl(8) to shorten the name of the boot environment – remove twenty-eight characters from the tail of the git hash, leave twelve
18. restart the computer
19. key Alt-F2 for ttyv1
20. login
21. nextboot -o "-s"
22. cd /usr/src && time make installkernel > & installkernel.log && history -S && shutdown -r now
23. /bin/csh
24. mount -uw /
25. zfs mount -a
26. kldload radeonkms
27. setenv EDITOR /usr/local/bin/nano
28. tail /usr/src/installkernel.log
29. check the tail of the third log for sanity
30. etcupdate -p
31. cd /usr/src && time make installworld > & installworld.log && etcupdate -B
32. tail -n 100 /usr/src/installworld.log
33. check the tail of the fourth log for sanity
34. make -DBATCH_DELETE_OLD_FILES delete-old && exit
35. pkg search drm-510-kmod ; pkg search drm-515-kmod
36. pkg lock -l
37. pkg lock emulators/virtualbox-ose-kmod drm-510-kmod graphics/drm-515-kmod
38. pkg upgrade --yes && pkg clean -a && pkg autoremove
39. sysrc sddm_enable="YES" && history -S && reboot -r
40. sign in to the desktop environment.

Additionally

For an existing poudriere jail named main with method src=/usr/src to gain an update equal to its host:

• sudo poudriere jail -u -j main

Then, have readily-available packages of ports that are special to you. For example:

• sudo poudriere ports -u && sudo poudriere bulk -j main -b latest -Ct emulators/virtualbox-ose-kmod drm-510-kmod graphics/drm-515-kmod graphics/gpu-firmware-radeon-kmod@btc graphics/gpu-firmware-radeon-kmod@sumo graphics/gpu-firmware-radeon-kmod@turks
