If the pkg.conf is configured with SIGNATURE_TYPE: FINGERPRINTS,
and FINGERPRINTS: /etc/keys/pkg then a pkg.sig file is fetched along
with pkg.txz. The signature contains the signature provided by the
signing server, and the public key. The .sig is the exact output
from the signing server in the following format:
SIGNATURE
<openssl signed>
CERT
<rsa public key>
END
The signature is verified with the following logic:
- If the .sig file is missing, it fails.
- If the .sig doesn't validate, it fails.
- If the public key in the .sig is not in the known trusted fingerprints,
it fails.
- If the public key is in the revoked key list, it fails.

In particular:
- Add a WITHOUT_TESTS variable that users can define to request that
no tests be put in /usr/tests.
- Add a top-level Kyuafile for /usr/tests and a way to create similar
Kyuafiles in top-level subdirectories.
- Add a BSD.tests.dist file to define the directory layout of

Scripts can request that the system reboot after the first boot by
creating the file ${firstboot_sentinel}-reboot.
This functionality is expected to be useful for embedded systems and
virtual machine images, where it may be desirable to
(a) download and install updates which became available between when
the image was created and when it was "turned on";
(b) download and install packages which may be newer than those
which were available when the image was created;
(c) install packages which run binaries during their install process,
bypassing the problem of cross-architecture installs;
(d) resize filesystems to match the disk onto which a VM image was
installed;
(e) perform initialization tasks relevant to cloud systems (e.g.,
Amazon's Elastic Compute Cloud);
and likely to perform many other one-time initialization functions.

Refactor of /dev/random device. Main points include:
* Userland seeding is no longer used. This auto-seeds at boot time
on PC/Desktop setups; this may need some tweeking and intelligence
from those folks setting up embedded boxes, but the work is believed
to be minimal.
* An entropy cache is written to /entropy (even during installation)
and the kernel uses this at next boot.
* An entropy file written to /boot/entropy can be loaded by loader(8)
* Hardware sources such as rdrand are fed into Yarrow, and are no
longer available raw.

Contains:
* Refactor the hardware RNG CPU instruction sources to feed into

to be sorted out. Modified by me (see below).
* Remove 'frac' parameter from random_harvest(). This was never
used and adds extra code for no good reason.
* Remove device write entropy harvesting. This provided a weak
attack vector, was not very good at bootstrapping the device. To
follow will be a replacement explicit reseed knob.
* Separate out all the RANDOM_PURE sources into separate harvest
entities. This adds some secuity in the case where more than one
is present.
* Review all the code and fix anything obviously messy or inconsistent.
Address som review concerns while I'm here, like rename the pseudo-rng

1) example (partially humorous random_adaptor, that I call "EXAMPLE")
* It's not meant to be used in a real system, it's there to show how
the basics of how to create interfaces for random_adaptors. Perhaps
it should belong in a manual page
2) Move probe.c's functionality in to random_adaptors.c
* rename random_ident_hardware() to random_adaptor_choose()
3) Introduce a new way to choose (or select) random_adaptors via tunable
"rngs_want" It's a list of comma separated names of adaptors, ordered
by preferences. I.e.:
rngs_want="yarrow,rdrand"
Such setting would cause yarrow to be preferred to rdrand. If neither of
them are available (or registered), then system will default to
something reasonable (currently yarrow). If yarrow is not present, then
we fall back to the adaptor that's first on the list of registered
adaptors.
4) Introduce a way where RNGs can play a role of entropy source. This is
mostly useful for HW rngs.
The way I envision this is that every HW RNG will use this
functionality by default. Functionality to disable this is also present.
I have an example of how to use this in random_adaptor_example.c (see
modload event, and init function)
5) fix kern.random.adaptors from
kern.random.adaptors: yarrowpanicblock
to
kern.random.adaptors: yarrow,panic,block

adaptor:

To assist this script, add an rc.subr command called "enabled" which

Add an rc script for unbound, called local_unbound. If there is no
configuration file, the rc script runs local-unbound-setup to generate
one.
Note that these scripts place the unbound configuration files in
/var/unbound rather than /etc/unbound. This is necessary so that
unbound can reload its configuration while chrooted. We should
