NTS: Use shred on tmpramfs/user.key if the system has it.

[noahbliss]

Note to self to investigate using the shred command if the system has it when we are performing the step 3 stage. Practical risk of not using shred should be negligible, we're already using a ramdisk, but if we have it, why not. :shrug:

If someone wants to start working on this, we should probably write a function for both 3- scrips that:

1. is invoked by trap if the user cancels the script. Otherwise is just called at the end of the script.
2. uses command -v to see if the system has shred
3. uses shred on tmpramfs/user.key, and uses rm if shred is not on the system.
4. Takes care of the rest of the process for collapsing the tmpfs.

Have you already done some work on this?
I might be able to help, if need be.
