In cross install, cannot mount fstab

[Haines Brown]

I am doing a cross install from my current Debian daedalus systm to a target 
disk /dev/nvme1n1.

I enter chroot, and create /etc/festab on the target. I use the UUIDs repored 
by # blkid for
the target disk,

Then I attemt to mount these partitions

        /:# mount -a 

Mount cann't find the UIIDs. For eample:

  mount: /tmp: can't find UUID="0753d3bf-15eb-40a3-bdbd-bea054fc4f60".

What am I doint wrong?
