Now, an ordinary user who is

Which is the exactly right question to ask.
The procedure documented is clearly flawed.
Probably a misunderstanding on my part, since I suggested it to Glen.
Can't
recall the circumstances exactly.
The next question would be: what is the correct procedure?
I'd guess the procedure involves shooting your feet:
from `sys/geom/geom_subr.c':
/* If foot-shooting is enabled, any open on rank#1 is OK */
if ((g_debugflags & 16) && pp->geom->rank == 1)
;
Well, yes. The goal is to unprotect the device, regardless of what may
already be on it. Then the user can overwrite it with the memory stick
image.
The current documentation is
sysctl kern.geom.debugflags=16
dd if=memstick.img of=/dev/whatever0 bs=64k
I presume that Poul-Henning was not claiming that the documentation did
not match the functional procedure, but rather that the procedure needed
to achieve the goal (of a functional USB stick) is flawed. (Even if it is
correctly documented.)
