Describe the feature

Some systems might be using tmpfs for / which requires additional configuration of the system

namely:

the kernel has to be compiled with initrc support
init needs to support toram option
The system has to have sufficient amount of tmpfs

Why would anyone want to do this?

Mostly tmpfs takes less power
tmpfs is usually much faster compared to HDD and SSD (could be even 100x faster)
On portable systems the tmpfs configuration might make the system much smaller allowing for more features alike bigger battery
Some RAM sticks are cheaper then HDD/SSD

Disadvantage

If your system loses power while being configured to run on tmpfs then you will lose ALL YOUR DATA, because tmpfs are not made to store memory without power

Note: Some systems might be configured to provide power to RAM even when it halts or turns off.

Expected behavior

Making zernit to run as small as possible from an SD card and create the system only from it's configuration directory to keep the size as small as possible.

The configuration directory should be mounted with persistance in case the end-user wants to do permanent changes to the system.

Vision

less then 10Mb/s file on SD card capable of booting the whole system anywhere.

Additional context

Debian has a live CD that does a decent job with this
