Hello I am not sure if I recall correctly, but I thought swap partitions were reported in the "mount" command output. I was not able to modify a drive today was the system thought it was in use, I found it a swap partition was mounted via "swapon -s" and called swapoff. Could I ask if swap partitions could be included in the output of "mount" please. Please keep my email address in any replies.
