Hello,
As of yesterday I stopped using m0n0image by Michael I and took most of the commands
from m0n0image and the hackers guide, along with the FreeBSD handbook, and tried to
write a new shell script that worked with mdconfig.
The shell script works great. It can successfully "decompress" an image and
"recompress" an image without any errors. However, whenever I boot from an image that the shell
script creates, it doesn't load. The boot up process stops at the kernel loading and it says it can't
find kernel or kernel.old.
I'm pretty sure I'm doing everything right. Maybe there's one mistake I'm completely
missing. Could someone please look at it and let me know?
Shell script is attached.
Thanks,
Matt
