It has a number of other, not really desired side effects as well.
1) Kernel people don't really like ramdisks anymore
2) Doing this requires mke2fs in the initramfs.  Bleah.
3) It puts an artificial cap on the size of your /dev that then has to
be adjustable.  And the cap is related to an overhead of memory usage.
This is ugly to get "right"
