In its current form this is an effective but dangerous install script. It will immediately nuke your /dev/sda and it won't apologize for doing so. Don't run this if that freaks you out.
Right now this is purpose built to install Arch to an EFI system with a single drive. It sets it up as follows:
- Erases drive
- Setups an EFI boot paritition
- Creates an encrypted / (root) and swap partition (no separate /home partition in this iteration)
- Installs Arch to the encrypted root
Note that half way through the script you will have to run
arch-chroot /mnt and then execute /postchroot.sh (I'm debugging why arch-chroot doesn't like to properly execute the script I send it).
