Thank you John,
>From my previous email (above) you will see the partitioning is totally
wack by /dev/sda2. Below you will find the partitioning portion of
the master script, up to the creation of the extended partition.
If DISK_SIZE=239372.437, then it doesn't make any sense to have
'$DISK_SIZE - 1' or -2 or -3. That has got to be wrong, but can I fix
it? Or maybe I don't understand what the output of '$DISK_SIZE - 1'
should be.
