EXPERIMENTAL
This tool writes a config.rktd file that you can point PLTCONFIGDIR and install packages into a place that isn’t the installation scope or the user scope.
The package environment overlays the system installation scope. There will probably be some hiccups if you are using this. Open some PRs and Issues.
Create a new package environment (from the shell):
;; make the environment
new-package> raco pkg-env _env
;; simple bash script that sets the PLTCONFIGDIR variable
new-package> source _env/activate.sh
;; install some-package into _env
new-package> raco pkg install some-packagename
