Alpine on the Laptop

Created: 2020-08-14T00:30:06.105824

Using a custom partition layout: you have to set the disks up yourself and run setup-disks, pointing it at the root to install Alpine at.
Particular challenge is getting cryptroot to decrypt the LUKS partition. syslinux didn't want to do this and had to prod around for the syntax/UUIDs to get in place.
Have to make an /etc/crypttab to tell the system to decrypt shit.
Make sure cryptsetup is in /etc/mkinitfs.conf's module list.
Make sure /etc/update-extlinux.conf is set up with the cryptroot flags.

Hard mode: btrfs subvolumes

Also include rootflags=subvol=@/alpine-sys since subvolumes are used to separate different areas of the system for snapshotting.
