                Install Arch Linux with Full Disk Encryption (LVM on LUKS)
              
          
    Based on:

https://gist.github.com/mattiaslundberg/8620837
https://wiki.archlinux.org/index.php/Installation_guide
http://www.muktware.io/arch-linux-guide-the-always-up-to-date-arch-linux-tutorial/ (Link is broken)

There are 2 choices:

UEFI/GPT mode: UEFI boot mode / GPT partition table
BIOS/MBR mode: Legacy boot mode / MBR partition table

I tried to install in UEFI mode, but my laptop (Acer E5-475-336H) had problems with it, and didn't boot after installation.

# Encryption functions. Requires the GNUpg "gpg" commandline tool. On OS X, "brew install gnupg"
# Explanation of options here:
# --symmetric - Don't public-key encrypt, just symmetrically encrypt in-place with a passphrase.
# -z 9 - Compression level
# --require-secmem - Require use of secured memory for operations. Bails otherwise.
# cipher-algo, s2k-cipher-algo - The algorithm used for the secret key
# digest-algo - The algorithm used to mangle the secret key
# s2k-mode 3 - Enables multiple rounds of mangling to thwart brute-force attacks
# s2k-count 65000000 - Mangles the passphrase this number of times. Takes over a second on modern hardware.
# compress-algo BZIP2- Uses a high quality compression algorithm before encryption. BZIP2 is good but not compatible with PGP proper, FYI.
