This is a slight refactor I found useful when debugging. The udevadmin info query will be visbile in the output of "set -x" which helps, and is the logs/journal. We can also reduce some calls by keeping the value and just grepping with a herefile. This also does some error checking and bails out if it does not see what it needs to continue.
