The usermgmt API was stomping on a global ($user_gid to be specific)
so things would appear to work fine until you tried to make a second
pass into the API with the now-tainted variable contents.
Fixed by localizing menu-specific contents as to not leak outside API.

Fix exit status when f_sysrc_set() fails. Errors in the underlying API
provided by bsdconfig(8) -- /usr/share/bsdconfig/sysrc.subr -- were not
being communicated back to the command-line. This was affecting ansible
modules using sysrc as they were not able to accurately test for error.

This command can be used by a sysadmin to either copy or migrate a data
file on one DS to another DS.
Its main use is to recover data files onto a mirrored DS after the DS has
been repaired and brought back online.
This command allows a sysadmin to display or modify the pnfsd.dsfile extended
attribute used by the pNFS MDS server in various ways.
Its main use is to set a DS's IP address to 0.0.0.0 when that DS has failed,
so that it will not be used for the file when brought back online after
being repaired.
kgdb now handles kernel module state internally, so the asf tool serves
no purpose.

This command can be used by a sysadmin to disable a malfunctioning pNFS server
mirrored DS. It is safe to use when a mirrored DS has already been disabled
via an I/O or network partitioning error.
The "-p" option specifies that the nfsd should run a pNFS service instead
of a regular NFS service. The "-m" option is only meaningful when used with
"-p" to specify that mirroring on the DSs should be done and on how many of
them.
This change requires the kernel changes committed as r334930.
The man page update will be committed as a separate commit soon.
allocation, I could identify that actually we use this pointer on pci_emul.c as
well as on vga.c source file.
I have reworked the logic here to make it more readable and also add a warn to
explicit show the function where the memory allocation error could happen,
also sort headers.
Also CID 1194192 was marked as "Intentional".

We no longer need to od these things conditionally, and the fallbacks
are to 4.2BSD era defaults, which nobody uses anymore. Vixie cron has
diverged from upstream anyway in our tree, and it's not clear there's
actually a viable upstream anymore. Plus, we don't follow the
vendor-supplied code pattern here.
I'm doing this to reduce false positives from grep.
given interval, which is counted in seconds since exit of the previous
invocation of the job. Example user crontab entry:
@25 sleep 10
The example will launch 'sleep 10' every 35 seconds. This is a rather
useless example above, but clearly explains the functionality.
The practical goal here is to avoid overlap of previous job invocation
to a new one, or to avoid too short interval(s) for jobs that last long
and doesn't have any point of immediate launch soon after previous run.
Another useful effect of interval jobs can be noticed when a cluster of
machines periodically communicates with a single node. Running the task
time based creates too much load on the node. Running interval based
spreads invocations across machines in cluster. Note that -j/-J won't
help in this case.

Some mpc85xx devices with u-boot need MBR partitioning with a FAT boot
partition. Since the infrastructure is already in place to have a dedicated
boot partition, this adds the necessary bits to use that infrastructure with
mpc85xx boards.

Summary:
The kernel reads 'kernelname' to set the kern.bootfile sysctl. By setting this,
'make installkernel' will backup the running kernel as appropriate.

This adds the -U options to pmcstat which will attribute in-kernel samples
back to the user stack that invoked the system call. It is not the default,
because when looking at kernel profiles it is generally more desirable to
merge all instances of a given system call together.
Although heavily revised, this change is directly derived from D7350 by
Jonathan T. Looney.
