# For the BSD types, there is a hierarchy that mostly resembles the
# class hierarchy in the sysinfo library;
# These are output strings of commands that sysinfo calls
#
# The test hierarchy is used as follows:
# Each operating system has its own _my_<OS>_subprocess_check_output
# call. If the call is not found, it calls it's 'parent' (e.g.
# for openbsd that is my_bsd_subprocesses_check_output).
#
# If that returns None, the call had no test value and the test fails
# (and needs to be updated).
# The child classes are checked first so that they can override
# output from the parents, if necessary.
#
# Some parents have their own parent
# (e.g. _my_freebsd_osx_subprocess_check_output), in that case,
# if they do not recognize the command, they simply return whatever
# their parent returns
