    I am not sure if the decision has been made.  The license charge
is for customer service we have essentially never needed and so it is
unpleasant to pay it - esp for the number of machines we run.  But
there are management issues with all other Linux choices as well...

So far as I know there are AIPS running on all of them.  The only OS
problem we have hit is with 64-bit computers that issue dynamic memory
from the top of the address range (using all 64 bits) while issuing
program memory from the bottom of the range.  AIPS' implementation of
dynamic memory fails in this case.
