I would suggest just getting the whole output of "blkid", then filtering
the lines you want with the "search" filter, and then using "regex_replace"
to get the bits you want, and finally passing those to the replace module.
Be aware, however, that "LABEL=/" is likely to match everything, so you
probably want to put some whitespace around the regex.
