Hello,
I wanted to change the name of the rescue media being created by rear. Instead of rear-$HOSTNAME I wanted to have the current datetime in the filename.

According to default.conf this can be achieved by setting $OUTPUT_PREFIX to a different value.

But this doesn't seem to work. The output file is always named rear-debian.iso (debian is in my case the hostname).

rear-debian.log

ISO image produced: 64170 sectors
Written to medium : 64170 sectors at LBA 0
Writing to 'stdio:/var/lib/rear/output/rear-debian.iso' completed successfully.

Question
Is there something I'm missing or is this a bug?

Thanks and best regards

My fault... To change the ISO filename ISO_PREFIX has to be used.
