For the last months, the tendency to encapsulate parts of the tool chain in a hierarchy of abstraction layers has been a high access barrier to make any use of the design tools. Can anyone point me to documentation • how to update a hierarchy of repositories (git submodule ...) when trying to update an existing installation of

caravel_user_project

or

caravel_user_project_analog

, as opposed to a complete reinstallation from scratch, because

git pull --all

leaves dangling, unresolved changes in submodules? • where to find the actual file system that gets installed by, e.g.,

make simenv

for someone who is familiar with analog IC design, but not with docker? • how to avoid running into compatibility problems caused by different, almost compatible installation instructions, the incompatibility of which forces me to reinstall everything from scratch because of subtle incompatibilities deep inside a virtualized (=inaccessible) stack of abstraction layers?
