The fix in /opt/cms/entrypoint.sh not working/enough in cmssw_10_6_30 to make mkedanlzr work

What happens:

After seeing some runtime problems with the PF Nano example in cmssw_10_6_30-slc7_amd64_gcc700:latest, I wanted to test the container with something simple, e.g. mkedanlzr.

Just to report what I see: mkedanlzr does not work (even with the fix in /opt/cms/entrypoint.sh) in cmssw_10_6_30-slc7_amd64_gcc700:latest. It an import error: ImportError: No module named FWCore.Skeletons.cms

I can confirm that with cmsenv, it behaves as on lxplus, i.e. builds the structure but does not give the configuration file (which I believe should be created). I do not know if this is intended but it looks to me that an example without the config file is pretty useless. It may be the whole mkedanlzr script has been abandoned. It would be a pity.

In any case, for the record, just reporting what I see in the container:

Background

See cmssw-docker#49 (closed) and https://github.com/cernopendata/data-curation/issues/114

/opt/cms/entrypoint.sh has a fix for the earlier CMSSW to make mkedanlzr work. And it indeed made it work for CMSSW_7_2_X.

(/code/CMSSW_10_6_30/src/Test) cat /opt/cms/entrypoint.sh
#!/bin/bash
set  -e

cd /code
echo "Setting up ${CMSSW_VERSION}"
source ${CMS_INSTALL_DIR}/cmsset_default.sh
scramv1 project CMSSW ${CMSSW_VERSION}
cd ${CMSSW_VERSION}/src
eval `scramv1 runtime -sh`
echo "CMSSW should now be available."
echo "This is a standalone image for ${CMSSW_VERSION} ${SCRAM_ARCH}."

export LD_LIBRARY_PATH=${UPDATE_PATH}/lib:${UPDATE_PATH}/lib64:${LD_LIBRARY_PATH}
export PATH=${UPDATE_PATH}/bin:${PATH}
export GIT_EXEC_PATH=${UPDATE_PATH}/libexec/git-core

# After CMSSW_6_2_X these steps are needed in order to ensure that
# mkedanlzr works
ver=( $(echo ${CMSSW_VERSION} | tr '_', '\n') )

if [[ ${ver[1]}${ver[2]} -ge 62 ]]
then

    if [[ ${CMSSW_VERSION} = *"patch"* ]]
    then
        BASE_VERSION=$(echo "${CMSSW_VERSION}"| cut -d '_' -f -4);
        CMSSW_VERSION=${BASE_VERSION}
    fi

   sudo sed -i '/import os/a import pwd' ${CMS_INSTALL_DIR}/${SCRAM_ARCH}/cms/cmssw/${CMSSW_VERSION}/python/FWCore/Skeletons/pkg.py
   sudo sed -i 's/os.getlogin()/pwd.getpwuid(os.geteuid())[0]/g' ${CMS_INSTALL_DIR}/${SCRAM_ARCH}/cms/cmssw/${CMSSW_VERSION}/python/FWCore/Skeletons/pkg.py

exec "$@"

Further checks

Checking in later versions on lxplus e.g. CMSSW_12_0_0, and it behaves as CMSSW_10 i.e. does not create the config file...
