Yes.

Well, finally I read the disklabel manual over again (about 3 times) and
I COULD add a new
partition on my boot drive!

This is typical. You know what, after googling for serveral hours, I
found out that
it did not let me write on the disk because the kernel had
SECURELEVEL=2. This is
something that should be in the manual. I appreciate that you wanted to
help me, but
actually you pointed me to the wrong direction two times.
I suggest to change the documentation of the disklabel/bsdlabel and
fdisk programs.
We should add this warning:
"Warning: you need to disable your kernel securelevel in /etc/rc.conf.
The kernel does not
allow to modify disk label information above securelevel=N."
(I'm still not sure about the value of N).
I'm not sure where can I add this request to change the documentation.
But it would save hundreds of hours for newbies and supporters too.
Best,
Les
