mounting uzip image: Invalid argument

[Erik Udo]

I'm making a live cd and i just hit a wall with uzip.

I started by creating a null 1GB file, which i filled with FreeBSD. 
After that i compressed the file with mkuzip.

Any attempts to mount this compressed image has failed, here is the 
output of truss when using mount_cd9660 to mount the image:

koti# truss mount_cd9660 /dev/md0.uzip testi

exit(0x1)
process exit, rval = 256

My system is FreeBSD 6.1-p11.

If anyone has any ideas on how to get this working, or what's wrong, 
please tell me.

Cheers,
