I'm trying to mount an image file (raspbian SD card image).
Under Linux I should use -o option of
mount
to define the offset of the second partition (ext2fs). As I understand, under FreeBSD I should use mdconfig
to create a device from img file and gnop
to create a second device with the offset needed.So I got the first device:
Code:
# gpart list md0
Geom name: md0
modified: false

Now I would like to mount my device to a directory - and I can't:
Code:
# mount -t ext2fs /dev/md0.nop /mnt/img

# gpart list md0.nop
gpart: No such geom: md0.nop.
The geom is here:

I can even
dd

What did I miss? How can I access this filesystem?
