Filesystems or Paths to be queried for free disk space as a SPACE

Results will be written to an attribute with leading slashes
removed, and other slashes replaced with underscore, and the word
'free' appended - e.g for /dev/sda1 it would be 'dev_sda1_free'.
Note: The root filesystem '/' is always queried to an attribute
named 'root_free'
