But in the nfs diskless case, we can do better by starting it a little
later. This disrupts nfs diskless on dynamic addresses a little, if it ever
actually worked with dhclient, but anyone doing that deserves the headache.

If NFS isn't compiled into the kernel, sysctl -n vfs.mounts.nfs
will produce no numerical output. Make sure that we always have
a valid arithmetic expression.

to perform network configuration (for example, "!route source -ifp em0")
Split mygate and myname manual pages (how did anyone ever believe these
are related), and perform hostname configuration much earlier in rc.

unwind can be started (silently) before pf is configured (for those
few weirdos who use hostnames in pf.conf...). Other unidentified concerns
may be improved by this startup re-ordering, so let's give it a try.

as a one-shot at boot without more complex kernel work, and also includes
some serial numbers/guids which may add a little more entropy e.g. for
systems where /etc/random.seed may be known (e.g. cloned disk images).

- put functions and data which are only used before calling the executable's
start function into their own page-aligned segments for unmapping
(only done on amd64, arm64, armv7, powerpc, and sparc64 so far)
- pass .init_array and .preinit_array functions an addition argument which
is a callback to get a structure which includes a function that frees
the boot text and data
- sometimes delay doing RELRO processing: for a shared-object marked
DF_1_INITFIRST do it after the object's .init_array, for the executable
do it after the .preinit_array
- improve test-ld.so to link against libpthread and trigger its initialization
late
libc changes to use this will come later

As of usr.bin/xinstall/install.c revision 1.68, -S is a no-op and
install(1) will always create files safely, thus clean the option usage
from the tree.

Loop over df(1)'s output directly, ensure the resulting list of block
devices is unique to avoid later duplicity checks and redundant mount(8)
invocations.
This allows direct bail out on invalid types and simpler saving for later
remount.

Many arm64 systems use device trees instead of ACPI and acpidump is
expectected to fail on those systems. And vmm(4) doesn't provide ACPI
information either.

to running VMs (at least for OpenBSD ones), but the stop routine for system
daemons is not usually called at shutdown.
Earlier version with just "vmd stop" ok reyk@ kn@, ajacoutot@ reminded me
to hide the contextless "vmd(ok)" text which looks bad, I did so and wrapped
it with a "stopping VMs" message (it can take some time, especially when you
have multiple VMs, so better to have some clear feedback).

sysctl_conf() spawns a subshell. This prevents that the new process
limits affect the daemons started during boot.

and to write the logfile inside the kernel compile dir.
- turn the whole reorder_kernel function into a subshell {} -> ()
- create kernel compile dir early on
- redirect all stdout/stderr to a logfile inside this dir
- setup ERR trap handler that
- disables the EXIT trap handler
- syslogs the error and hints to the logfile
- additionally sends this message to the console
- setup EXIT trap handler that syslogs success
- wipe only the content instead of the whole kernel compile dir
- reestablish stdout redirection to the log after the wipe
- remove -q option of sha256 to log check result
- run reorder_kernel() in the background
OK deraadt@ tb@

- check for and exit if /usr/share is on a nfs mounted filesystem
- add trap handlers that mail the logfile to the admin user
- use $_compile instead of $_compile_dir like in the installer
- use $_compile/$_kernel instead of $_kernel_dir
- remove the now redundant sha256 -h ... after make newinstall
- write stdout/stderr of the background subshell to a logfile

presume we booted from. If you boot from another kernel, we cannot help
you later with hibernate, sorry -- The kernel does not get a useable
filename from the bootblocks.
In the bootblocks, detect a live hibernate signature and boot from
/bsd.booted instead.

new kernel in the background on system startup. It stores the hash
of the new kernel and sends a notification email to the admin or
root user. If it finds /usr/share/compile.tgz, it removes the
existing compile dir and replaces it with the content of (new)
archive. If the hash of /bsd does not match the stored one, no
relinking happens.
