I'm having problems getting a 8.1 nanobsd image to boot on a Soekris
5501. It is perhaps easiest to show what happens when I power on the
5510 with the compact flas installed:

FreeBSD/i386 bootstrap loader, Revision 1.1

/boot/kernel/kernel text=0x8c9a23 data=0xde2b4+0xa3fb0 syms=[0x4+0x98450+0x4+0xd0405]
Hit [Enter] to boot immediately, or any other key for command prompt.
Booting [/boot/kernel/kernel] in 8 seconds...
Type '?' for a list of commands, 'help' for more detailed help.
OK boot -s
\
And then here it simply hangs. I've let it sit for hours and it never
does anything.
One thing I noticed is that /boot/loader on the nanobsd image is
different from /boot/loader on my workstation. If I copy /boot/loader
from my FreeBSD 8.1 workstaiton onto the CF nanobsd image then I get
alot further. Clearly NanoBSD is building the loader differently,
mostly because before I never got the beastie loader menu, and now I
do. But I also get the kernel to actually start, or at least emit
messages as it starts:

ROOT MOUNT ERROR:
If you have invalid mount options, reboot, and first try the following from
the loader prompt:
set vfs.root.mountfrom.options=rw
and then remove invalid mount options from /etc/fstab.
Loader variables:
vfs.root.mountfrom=ufs:/dev/ad1s1a

<fstype>:<device> Mount <device> using filesystem <fstype>

This is equivalent to: mount -t cd9660 /dev/acd0 /

I looked around and didn't find in nanobsd.sh any obvious knobs that
changed how /boot/loader was built. I was wondering if anybody had any
insights.
