Allow live boot to access app storage #112
Description
The live boot of HolOS currently runs all in memory. This prevents us from being able to start docker containers, due to an issue between the pivotroot call and the initramfs driver. It would be helpful to be able to be able to use a local drive as persistent application storage. This would allow someone to live-boot HolOS and try it out, using a spare drive for application persistence. If we label this filesystem to match the installer's data volume, the user could then install HolOS at a later date, and keep their application data. This would also allow someone to live-boot a new version of HolOS, without installing it, and access all of the existing application data. To revert, they could simply reboot into the installed version.
Not a huge amount of work, but improves our flexibility and usability.
