Encrypted Btrfs storage setup and maintenance guide

Initial setup with LUKS/dm-crypt

This exemplary initial setup uses two devices /dev/sdb and /dev/sdc but can be applied to any amount of devices by following the steps with additional devices.

Create keyfile:

dd bs=64 count=1 if=/dev/urandom of=/etc/cryptkey iflag=fullblock
chmod 600 /etc/cryptkey

# extract_cookies.sh:
#
# Convert from Firefox's cookies.sqlite format to Netscape cookies,
# which can then be used by wget and curl. (Why don't wget and curl
# just use libsqlite if it's installed?)

# USAGE:
#
# $ extract_cookies.sh > /tmp/cookies.txt
