   Yes, I am using plain dm-crypt:

     cryptsetup -d ${KEYFILE} create container1 /dev/loop1

Thanks for the advice. I am now able to mount the container using the 
latest packages using:

     cryptsetup -c aes-cbc-plain -h ripemd160 -s 256  -d ${KEYFILE} 
create container1 /dev/loop1

Just the cipher seemed to do the trick but I expect the other options 
will protect me from future changes.  I should probably start using 
crypttab - I didn't know what it was before.

Thanks again
David
