Sorry, wrong name: --installpath-modules If you are not using this explicitly in your config, then you are relying on EASYBUILD_PREFIX to set the default, see https://docs.easybuild.io/en/latest/Configuration.html#mandatory-configuration-settings for details. By setting _just_ EASYBUILD_INSTALLPATH, you are only changing where software gets installed, everything else is remaining the same (and EasyBuild relies only on the module files to know if something is installed or not).
