034669e856 rc: replace NETWORK with NETWORKING
This improves consistency; the NETWORKING script provides both,
so there should be no functional change.

82431b7506 rc: remove the 'archdep' script
It was unused since 405c3050f1, which removed iBCS support.

This also moves the 'linux' rc script slightly earlier, which
might help in some setups.  The original version of this patch
moved it even more, before 'mountcritlocal', which would fixe
mount(8) errors due to missing /dev/shm in setups with entries
for /path/to/chroot/dev/shm without the "late" flag; however,
in the end 'kldxref' turned out to depend on 'mountcritlocal'
anyway.

08bfbd4359 rtld: workaround for broken ABI
Right now, libthr does not initialize RtldLockInfo.rtli_version when calling
_rtld_thread_init(), which makes versioning the interface troublesome.

Add a workaround: if the calling object of _rtld_thread_init() exports
the "_pli_rtli_version" symbol, then consider rtli_version initialized.
Otherwise, forcibly set it to RTLI_VERSION_ONE, currently defined as
RTLI_VERSION.

Export "_pli_rtli_version" from libthr and properly initialize rtli_version.

f30f11f878 wait for device mounts in zpool and dumpon
If the root file system is composed from multiple devices, wait for
devices to be ready before running zpool and dumpon rc scripts.

An example of this is if the bulk of the root file system exists on a
fast device (e.g. NVMe) but the /var directory comes from a ZFS dataset
on a slower device (e.g. SATA). In this case, it is possible that the
zpool import may run before the slower device has finished being probed,
leaving the system in an intermediate state.

Fix is to add root_hold_wait to the zpool and dumpon (which has a
similar issue) rc scripts.

This may be used to optimize a loading process - in the case when
we already have a file descriptor to the library; we don't have
to look into multiple PATH to find it.

It may also be used in capability mode to load a single additional
library without the need to open a directory that contains it.

The last use of this functionality t may be a race-free method
of loading libraries.

09673fc0f3 mountd(8): generate a syslog message when the "V4:" line is missing
Daniel reported that NFSv4 mounts were not working despite having
set "nfsv4_server_enable=YES" in /etc/rc.conf.  Mountd was logging a
message that there was no /etc/exports file.
He noted that creating a /etc/exports file with a "V4:" line in it
was needed make NFSv4 mounts work.
At least one "V4:" line in one of the exports(5) file(s) is needed to
make NFSv4 mounts work. This patch fixes mountd.c so that it logs a
message indicting that there is no "V4:" line in any exports(5)
file when NFSv4 mounts are enabled.
To avoid this message being generated erroneously, /etc/rc.d/mountd
is updated to make sure vfs.nfsd.server_max_nfsvers is properly set
before mountd(8) is started.

6e822e9957 rc: fix parse of $local_startup
77e1ccbee3 introduced parallel execution
of rc. It separated groups with line feeds (\n) and elements within
groups using spaces. This is a natural separation due to rcorder
using spaces and lines to separate elements within groups with groups
of services separated by line feeds.

77e1ccbee3 parses the output from rcorder
by setting $IFS. However it failed to reset $IFS to default ' \t\n'
prior to calling find_local_scripts_new(), causing find_local_scripts_new()
to fail parsing $local_startup for site-specific local rc scripts, i.e.
${LOCALBASE}/etc/rc.d. This caused daemons from ports and packages such
as postfix, dovecot, nut, and others in ${LOCALBASE} not to be started.

24f44a445c Remove dependency on files in /usr/bin
In order to reduce the pre-requisites of this file, implement the
pattern matching and creation of a temporary test directory without
use of grep respectively mktemp.

The new version makes it possible to provide a writable /tmp in any
case and independently of other local or remote file systems (except /
and /dev) being mounted.

The use of "dd if=/dev/random" has the same dependency on /dev/random
being operational as the previous version that used "mktemp". If this
is found to be an issue on platforms that do not have gathered
sufficient entropy at the time when this scriot is run, I suggest to
replace the "dd" command with "ps lauxww" to get a somewhat random
