Hi there - I'm trying to use picobsd on freebsd 5.3 and having a few problems.

I am simply doing "/usr/src/release/picobsd/build/picobsd bridge" as
root, accepting all the defaults and selecting 'build' from the
dialog.  It sucessfully compiles the kernel, does crunchgen ok (with a
few errors re: sshd which im confident I can fix in crunch.conf
later), and then starts to build the floppy image and dies like this:

        bsdlabel -R -B [-n] [-b boot] [-m machine] disk protofile

---> fail: Error <1> error code <floppy_disklabel> in <>
Error while doing disklabel on of floppy.img size 1440
---> Aborting ./picobsd

I added an echo of what seems to be the command that causes it to
fail, you can see it in the output above but I'll also put it here:
disklabel -Brw -b /boot/boot1 -s /root/pico/build_dir-bridge/boot2 md0 auto
I'm pretty new to freebsd so I have no idea what that command is
trying to achieve, but perusing the disklabel manpage shows no -r or
-s arguments, and a quick look at
shows that those options were both added in v1.29 (as well as a bunch
of other things), which is the version that in 5.3.

My end goal is to just end up with a kernel file (with embedded
ramdisk image) that I can boot with grub (from a cf card), but I'm not
sure how to fix the script to get there.

Any suggestions would be great.
