Class for parsing the `/usr/libexec/setup-named-chroot.sh` file.
Typical content of the filtered file is::

# it MUST be listed last. (/var/named contains /var/named/chroot)

Attributes:
raw (list): A list of all the active lines present
Raises:
SkipComponent: When the file is empty or when the input content is not
empty but there is no useful parsed data
Examples:
>>> len(snc)

>>> snc['ROOTDIR_MOUNT']
