I need info to make memstick.img for GhostBSD project.
If some one have an how to to make an memstick image.
Please reply.
thanks
 
Code: 
# make 2GB image file:
  dd if=/dev/zero of=./memstick.img bs=1m count=2000

# load image as virtual disk device:
  mdconfig -a -t vnode -f ./memstick.img -u 0

  fdisk -iI /dev/md0
  bsdlabel -wB /dev/md0s1
  newfs /dev/md0s1a

  mount /dev/md0s1a /mnt
  cd /usr/src
  make installkernel installworld DESTDIR=/mnt
  umount /mnt

# insert memstick now, assuming it will be /dev/da0...
# raw copy virtual disk content to memstick.
  dd if=/dev/md0 of=/dev/da0 bs=1m

Don't forget to configure /etc/fstab to mount / from USB
 
If you already have an image which will fit on the memory-stick you can try

Code: 
dd if=/dev/zero of=/dev/da0 bs=1k count=1

bsdlabel -Bw da0 auto

newfs -L FreeBSD /dev/da0a

mdconfig -a -t vnode -f X.Y-IMGFILE -u 0 && mount -r -t cd9660 /dev/md0 /mnt/iso

mount /dev/da0a /mnt/USB-Stick

copy all files from your mounted cd in to your USB-Stick, after that you need to create a fstab for your USB-Stick

vi /mnt/USB-Stick/etc/fstab and put following in:

/dev/ufs/FreeBSD / ufs ro 0 0

It confused me for some time:
why "copying all files" will do the job. Aren't we supposed to also install boot loader (or something alike) into the MBR of the img?
