Reorganize how RAM disks are created

This improves things by moving the read of the sizes for the RAM disks

RAM disks.

Simplify these calculations by doing them directly in the shell

RAM Disk robustness improvements. Fixes NG 3173

• Prevents RAM disk from being partially enabled and left in a broken
