Those warnings are thrown for each 'SINGULARITYENV_' var that does not 
have a corresponding 'APPTAINERENV_' var and this was addressed in 
HTCondor 9.0.17 and 9.10.0 here: 
https://opensciencegrid.atlassian.net/browse/HTCONDOR-1137. It turned 
out that the factory config needed to be updated for 9.0.17 but that's 
done so new pilots should not have this problem. Let us know if you 
continue to see it on new pilots!
