Thanks for the info.
I have also seen in various places online that the 40-generic.conf file is obsolete and can be removed. Doing that also fixes the warnings. I am not well versed in fonts, do we need that file? If so, I can add a data .tar.gz file with a fixed 40-generic.conf. But if not, it is simpler to delete the file with a deb2sce startup script.
