Changes made after installation:

The script /etc/init.d/unoconvd
was changed in two places:

#!/bin/sh instead of #!/bin/bash
Calling unoconv:
/usr/bin/unoconv --listener &

In the script /usr/local/bin/pdf-konverter.sh
this change to the shell call was made:
#!/bin/sh instead of #!/bin/bash

The mime-construct program is no longer used because
the filename was not coded, and therefore with some email
clients was not represented properly.
The email now uses the echo command and the uuencode
program (from the sharutils package) handed
directly over to the sendmail command from Postfix.

In the pdf-konverter.sh script, some output is logged in text files, which is helpful when troubleshooting.
