Saving a snapshot is pretty much exactly how the sysimg that is shipped with Julia is built.

in the Makefile and the `contrib/generate_precompile.jl` is what we put into the sysimg:

Where the REPL gets started, a few things gets evaluated and some Pkg commands are run. Then a snapshot of that is saved.
