ERROR: Making backup on / is forbidden. Use an external device!

[dagwieers]

When doing rear mkrescue using the following configuration:

OUTPUT=ISO
ISO_URL=file:///tmp/test.iso

BACKUP=NETFS
BACKUP_URL=usb:///dev/disk/by-label/Pack

I get the following error:

[root@moria rear]# rear -v -D mkrescue
Relax and Recover 1.13.0 / $Date$
ERROR: Making backup on / is forbidden. Use an external device!
Aborting due to an error, check /tmp/rear-moria.log for details
Finished in 0 seconds
Terminated

This problem occurs in: prep/NETFS/default/40_automatic_exclude_recreate.sh

Even when using OUTPUT_URL it will fail with the above error. If I don't set ISO_URL or OUTPUT_URL I have another problem:

Relax and Recover 1.13.0 / $Date$
