I made
cache_dir
configurable through an environment variable. Some CI impose some restriction on the location of what can be cached. For example, Gitlab CI mandates that the cache directory be a children of the build directory. Andpdm config cache_dir
is hardly usable when you have a big CI configuration where many blocs override each others.I saw the
$HOME
tricks recommended by the env var but I think it would break our code base.
