Space Limitations: Upgrade SDs or Find files to cut out

[Zacharyprime]

We have been reaching this point for some time, but 8GB is cramped. Half of this space is taken up by /usr/lib, which makes a bit of sense.

We might be able to cut out a significant amount by using executables for installation rather than building straight from GitHub. There are probably lib files that can be eliminated with this, we would just have to keep larger SDs for the development team to use.

Here are the sizes of some notable directories/files:

The exact sizes shown might vary system to system as v27 can be built from scratch on any Debian based OS. The build this is from is a Wombat starting on Raspberry Pi OS following these steps (roughly, this gist changes as I fix things).

We have discussed this in other places since this post was made.

We will likely upgrade in the future but for now 8GB works.
