1d79f30229 Revert r282672.
tr is in /usr and not available at the time hostid is run (must be run
before FILESYSTEMS).

86fdaae573 Replace ${SYSCTL_W} with ${SYSCTL} in rc.d scripts, as they are identical.
This is a further clean up after r202988.

SYSCTL_W is still initialized in rc.subr as some ports may still use it.

2822c33f8c This change does the following for the scripts that run up through
FILESYSTEMS (the default early_late_divider):
1. Move sysctl to run first
2. Move as many BEFOREs to REQUIREs as possible.
3. Minor effect, move hostid_save from right before mdconfig to right
   after.

A lot of the early scripts make use of sysctl one way or another so
running this first makes a lot of sense given that system-critical
values are often placed in sysctl.conf.

My original purpose for working on this was that while doing some
debugging on other stuff I noticed that the order of execution was
different in the first pass through the early scripts and the second.
In practice that doesn't matter because the scripts are not executed the
second time. However this _can_ result in problems if the difference in
the rcorder moves a script from the late section to the early section in
the second pass (which would mean the script would not get executed).
So, I wanted to make the order of execution of the scripts in the early
section more deterministic.

In the course of debugging the ordering problems I noticed that moving
the BEFOREs to REQUIREs prevented the changes in order from the first
pass to the second pass without having to make any substantial changes.
(Of course it's no secret that I think BEFORE should be avoided as much
as possible, but this is a good example of why.)

70d4ef1ea1 In regards to the "Starting foo:" type messages at boot time, create and
employ a more generic solution, and use it in the individual rc.d scripts
that also have an $rc_quiet test:

1. Add check_startmsgs() to rc.subr.
2. In the rc.d scripts that use rc_quiet (and rc.subr) substitute
variations of [ -z "$rc_quiet" ] with check_startmsgs
3. In savecore add a trailing '.' to the end of the message to make it
more consistent with other scripts.
4. In newsyslog remove a : before the terminal '.' since we do not expect
there to be anything printed out in between to make it more consistent.
5. In the following scripts change "quotes" to 'quotes' where no variables
exist in the message: savecore pf newsyslog
6. In the following scripts substitute if/then/fi for the simpler (and
more consistent) check_startmsgs &&: faith stf
7. In the following scripts separate the "Starting foo:" from the terminal
'.' to make them more consistent: moused hostname pf
8. In nfsclient move the message to its own line to avoid a style bug
9. In pf rc_quiet does not apply to the _stop method, so remove the
test there.
10. In motd add 'quotes' around the terminal '.' for consistency

d5d7e76d2b Currently there is a problem with fscking UFS file systems created on
top of ZVOLs. The problem is that rc.d/fsck runs before rc.d/zfs. The
latter makes ZVOLs to appear in /dev/. In such case rc.d/fsck cannot
find devfs entry and aborts. We cannot simply move rc.d/zfs before
rc.d/fsck, because we first want kern.hostid to be configured (by
rc.d/hostid). If we won't wait (hostid will be 0) we can reuse disks
which are in use by different systems (eg. in SAN/NAS environment).
We also cannot move rc.d/hostid before rc.d/fsck, because rc.d/hostid on
first system start stores generated kern.hostuuid in /etc/hostid file,
so it needs root file system to be mounted read-write.

The fix is to split rc.d/hostid so that rc.d/hostid (which will now run
before rc.d/fsck) only generates hostid and sets up sysctls, but doesn't
touch root file system and rc.d/hostid_save (which is run after
rc.d/root) and only creates /etc/hostid file.

With that in place, we can move ZVOL initialization to dedicated
rc.d/zvol script which runs before rc.d/fsck.

dff50af93b Remove the ugly csh(1) based UUID lower-case translation hack from
/etc/rc.d/hostid now that we switched the origin of the UUID (variable
smbios.system.uuid as provided by the i386 BIOS code) to already provide
a standard conforming lower-case UUID text representation.

e3e421bacf Cleanup style by consistently using braces around variable expansion and
apply an addition from Andrew Thompson <thompsa> for filtering out the
special "Nil" UUID (all zeros) which would be a useless host UUID.

3148ce8687 Adjust UUID lower-case translation from straight-forward tr(1)
usage to an equivalent csh(1) usage as tr(1) stays in /usr/bin and
/etc/rc.d/hostid has just the root filesystem (and this way mainly the
tools in /bin) available.

I've chosen csh(1) here as the string manipulation tools available in
/bin is extremely limited and the (only) alternative ed(1) usage would
have been a lot more complicated or even might require a temporary file.

a8698e63bb The standardized textual representation of UUIDs according to RFC 4122
and ISO/IEC-9834-8:2005 is with LOWER-CASE hexadecimal characters only,
so translate the (usually upper-case and this way not conforming)
representation of the BIOS UUID when reading it. Also be more strict
about the valid characters in the textual representation by checking for
just the hexadecimal characters.

6f7c3bdd63 If available, take UUID from smbios.system.uuid, if not fall back to
software-generated UUID. Store the result in /etc/hostid and use it in
the future. Perform simple UUID format check, as there is a lot of
hardware with broken UUIDs. The check should be improved to also eliminate
fake UUIDs like 00000000-0000-0000-0000-000000000000.

d5ec19ea68 Add rc.d/hostid script (turned on by default) which on first boot generates
UUID and stores it in /etc/hostid ($hostid_file) as well as sets kern.hostuuid
and kern.hostid sysctls on every boot.

Hostid can be reset using '/etc/rc.d/hostid reset' command.

Hostid generation and setting can be turned off by setting variable
hostid_enable to "NO" in /etc/rc.conf.
