Host types have been moved within the `bootstrap` package.
Refactored how boostrap FS is interacted with. There is now a
`Bootstrap` struct which has pre-loaded all data within the bootstrap
FS. This helps centralize the logic around reading the data (though not
yet completely).
Choosing of the garage node to interact with no longer occurs in like
three different places. It occurs at the environment level now, and is
aided by the new `garage.Peer` type.
There has been over 1 year of commit history leading up to this point,
but almost all of that has had some kind network configuration or
secrets built into the code. As of today all of that has been removed,
and the codebase can finally be published!
I am keeping a private copy of the previous commit history, though it's
unclear if it will ever be able to be published.
