I guess after the first installkernel, to default location, I should immediately make installkernel again, this time with DESTDIR=/mnt?
Better to "make buildkernel" and "make installkernel" as two separate steps, rather than "make kernel"?
After rebooting single-user, do "mergemaster -p", then "mergemaster -p -D /mnt", and then "make installworld" and immediately following that, "make installworld DESTDIR=/mnt" ?
After that, I would do "mergemaster -i" followed by "mergemaster -i -D /mnt"? And then make delete-old followed by "DESTDIR=/mnt make delete-old"?
Would I need to do "make distribution"?
First time, "make installkernel DESTDIR=/mnt" only installed part. I installed to USB stick only after fully upgrading on main installation, finally copied /boot/kernel directory, and that USB stick is now bootable. So now I know how to make a USB stick bootable with GPT.
Maybe some of the files were cleaned out?
It is surely useful to have a rescue backup, considering the possibility of an update going awry on the main installation.
