Hi all!!,

And could be possible... doing something like :

mdconfig -a -t vnode -f /tmp/bootable.iso -u 0
# mount -t cd9660 /dev/md0 /mnt


And later an rsync -av (rsync compiled preserving file flags) /mnt 
/expert/netboot/freebsd90... ??

and the most important thing... could this content in 
/expert/netboot/freebsd90 be consistent for using it for an unattended 
installation system?

Thanks a lot!!
Best regards,
