Thanks. I managed to pick-up the changes in sys/boot the hard way.

I did an installworld before seeing your mail, so I did not test boot1 boot2
and loader separately.

The good news is they really fix the issue I was having:

I tried to upgrade a machine to a hammer / with a spare 500GB drive, and for
some reason the PC kept rebooting just after displaying the first boot
messages "F1 DF/FBSD" and "F5 Drive 1"
I couldn't see if there was a "BTX halted" message, the screen blanked too
quickly for that.
The same machine had no trouble with a 400GB drive and an UFS root.

With your new boot blocks, the system boots as it should.
Thank you, I'm a happy bunny now :-)

Well, it didn't occur to me I would have had to create my own branch. Beeing
only used to cvs and svn, git is really a strange animal.
