(get command) or if the current value is the same as what is desired
(set command). In those cases, the return status is success.
Otherwise, if the variable is unset (get command) or set to a different
value that what is desired (set command), returns with error status.
This is useful for puppet integration as well as everyday scripting.
Do not inherit $SYSRC_VERBOSE from operating environment. The concern is
that when a user (such as myself) which has SYSRC_VERBOSE=1 in his/her
~/.bash_profile or such that when they are told to execute a command like:
hostname `sysrc -n hostname`
NOTE: To activate a recently configured hostname.
If $SYSRC_VERBOSE is set, then POLA is violated because the output of sysrc
is indirectly influenced (making for an inconsistent experience).
disconnected under the WITH_BSDCONFIG flag (a good idea since this version of
sysrc(8) indeed requires the `sysrc.subr' module installed by bsdconfig(8)).
Multiple reasons sysrc should not simply continue to live in ports. The most
important being that it is tightly coupled with the base.
