I tried adding

    & File.dirExists \"/mnt/nfs\"
    & \"/etc/fstab\" `File.containsLine` \"192.168.1.100:/mnt/usb1 /mnt/nfs nfs intr 0 0\"
      `onChange` cmdProperty \"mount\" [\"-a\"]

This mimicks the bitlbee example on /usr/local/propellor/config-joey.hs

But that results:

    src/config.hs:36:11:
        No instance for (Combines
                           (Property NoInfo) (UncheckedProperty NoInfo))
          arising from a use of ‘onChange’
        In the second argument of ‘(&)’, namely
          ‘\"/etc/fstab\"
           `File.containsLine` \"192.168.1.100:/mnt/usb1 /mnt/nfs nfs intr 0 0\"
           `onChange` cmdProperty \"mount\" [\"-a\"]’
