Andrea, you will have to install 'mkudffs' if you don't mind.  I looked on the internet, and it appears to be available for Arch.


Following Phyllis' instructions (BD render) I render up to 100% and
then I have these errors (from root):


+ mkudffs -b 2048 /tmp/bd_20220502-182538/bd.udfs 26524
/tmp/bd_20220502-182538/bd.sh: line 14: mkudffs: command not found
