You could do it as done in the m0n0wall hackers guide.
This is how i do it:
On your BSD 4.8 host machine:
Make a folder, and download the latest net45xx or generic-pc image to
Rename the file, and append ".gz" to the filename eg:
Decompress the image with: 'gzip -d net45xx-pbXXrXXX.img.gz'
Use vnconfig: 'vnconfig -s labels -c vn0 net45xx-pbXXrXXX.img'
Mount the image: 'mount /dev/vn0a /mnt'
Copy the mfsroot.gz from /mnt to a location of your choice.
Unmount: 'umount /mnt'
Unlink image: 'vnconfig -u vn0'
Uncompress the mfsroot.gz file: 'gzip -d mfsroot.gz'
Vnconfig again, the filesystem now: 'vnconfig -s lablels -c vn0 mfsroot'
Mount the image: 'mount /dev/vn0 /mnt'
Do any changes you like to the rootfilesystem in the /mnt directory,
Do unmount again: 'umount /mnt'
And unlink: 'vnconfig -u vn0'
Compress the image: 'gzip -9 mfsroot'
Mount the net45xx.img: 'vnconfig -s labels -c vn0 net45xx-pbXXrXXX.img'
And: 'mount /dev/vn0a /mnt'
Copy your modified mfsroot.gz into /mnt
Unmount: 'vnconfig -u vn0'
And: 'umount /mnt'
Compress your new image: 'gzip -9 net45xx-pbXXrXXX.img'
And upload it!
Preferrably you would make a shell script to do this for you...
Same procedure could also be used to replace the kernel in the
generic-pc image. Of course then you would have to build a new
