Update to R 4.2.2 and RStudio 2024.09.0, Build 375.
Make it possible to call ./rstudio exec -i (instancename) COMMAND to non-interactively execute commands inside an instance, which will be started if necessary.
Also, this moves away from storing the scripts inside the container that are meant to be outside (previously were extracted using
the "setup" script which was copied into the container). Just packing them into a zip is easier for now.
