Arch Linux LUKS Encrypted / on Btrfs Raid 0 (Stripe) of 2 Drives

General

Info

!ATTENTION! This script is intentionally designed to completely wipe all data on at least two drives! !ATTENTION!

# Mersenne Twister predictor

# need to see the first 624 values, just *any* 624 consecutive values. The
# seed used is also irrelevant, and it will work even if the generator was
