making an ISO image

[Rob Whyte]

Hi,

mount -a reads your /etc/fstab file.

If sda2 is in that file and has the location as /mnt yes it would work.

But it is unlikely.


So that is why you need to specify the partition, being /dev/sda2 and
the mount point which is /mnt

mount /dev/sda2 /mnt

 

Good luck

Rob
