updating 15.0-CURRENT from ~ 3 weeks ago to 15.0-ALPHA1

NB I built my own pkgbase set, based off stable/15 @ 0b3d82579a01db4c5d874cda1ac468bb8f26c109

The overall plan is:

1. upgrade only the GENERIC kernel package from my pkgbase set
2. reboot
3. upgrade all the remaining base system packages from my pkgbase set
4. update the EFI boot loader from the just-installed FreeBSD-bootloader
5. re-bootstrap pkg for the new userland from the public pkg.freebsd.org packages
6. delete all non-base system packages to remove a few years of cruft
7. install my minimal useful package list
8. reboot again
9. install all the toys
10. celebrate

In practice I didn't quite follow this recipe, but close enough.

upgrade just the kernel first, and reboot

reboot here & see if this all works

Indeed it does. Install the rest while enjoying a well-deserved beverage.

Naive Upgrade 14.3 non-pkgbase to 15 pkgbase

This would almost certainly be better with pkgbasify but YOLO gotta YOLO

# pkg -o ABI=FreeBSD:15:amd64 upgrade -r pkg-base FreeBSD-kernel-generic
# shutdown -r now

That worked, let's keep going. Gotta bootstrap pkg first tho.. nope why isn't ABI respected?

# pkg -o ABI=FreeBSD:15:amd64  bootstrap -f

that seems better?

OK I'm expecting this to break midway through.

# pkg -o ABI=FreeBSD:15:amd64 install -r pkg-base -g FreeBSD-\*

OK it didn't bork, so lets add the loader and clean up

# cp /boot/loader.efi /boot/efi/efi/freebsd/loader.efi
# rm -rf (fd pkgsave / |grep -v /etc |head -10000)
# rm -rf (fd pkgsave / |grep -v /etc |head -10000)
# rm -rf (fd pkgsave / |grep -v /etc |head -10000)

now etc

# cd /etc/
# rm rc.d/*.pkgsave defaults/*.pkgsave ssl/*.pkgsave mtree/*.pkgsave rc.*.pkgsave ttys.pkgsave
# rm devd/*.pkgsave net*.pkgsave mail/*.pkgsave periodic/*/*.pkgsave
# rm devd.conf.pkgsave gettytab.pkgsave gss/mech.pkgsave inetd.conf.pkgsave \

  phones.pkgsave pkg/FreeBSD.conf.pkgsave printcap.pkgsave protocols.pkgsave \
  rc.pkgsave regdomain.xml.pkgsave remote.pkgsave services.pkgsave shells.pkgsave \
# mv sysctl.conf.pkgsave sysctl.conf

now serious stuff

# mv master.passwd.pkgsave master.passwd
# mv group.pkgsave group
# vipw
vipw: password list updated
# rm ssh/moduli.pkgsave

append these custom settings to sshd_config

Port 2200
PermitRootLogin prohibit-password
KbdInteractiveAuthentication no
UsePAM no
UseDNS no

lets see if this boots (15.0-ALPHA1 but old userland)... it does! well well.

now we can do the pkg dance from before:

• bootstrap
• stash list of packages
• upgrade everything
