Let init(8) and reboot(8) use utmpx to log wtmp entries.

logwtmp() gets called with the raw strings that are written to disk. For
regular user entries, this isn't too bad, but when booting/shutting

Let init(8) and reboot(8) use utmpx to log wtmp entries.

logwtmp() gets called with the raw strings that are written to disk. For
regular user entries, this isn't too bad, but when booting/shutting
down, the contents get rather cryptic.

Just call the standardized pututxline().

MFC @199204

Switch the default WARNS level for sbin/ to 6.

I understood the MLINK part incorrectly, it should be the other way around
also remove the init mlink to securelevel.

Discussed with and sharing pointyhat with: brueffer

use standard mode instead of 500 for /sbin/init.

As discussed on -current, there is no sensitive info in /sbin/init

use standard mode instead of 500 for /sbin/init.

As discussed on -current, there is no sensitive info in /sbin/init
to prevent reading it from non-privileged users, nor any reason to
remove the 'x' bit as the first thing the program does is check the
uid and exit if it is not run by root.

Instead (and this is why i make the change), mode 500 prevents
operation when exporting the partition without -maproot=0 to diskless
clients.

All previuos releases are affected by the same problem, so a merge
to RELENG_6 at least would be appropriate (after proper re@ approval
of course).

Make WARNS=6 happy with our init(8):
- Use more ``const''s where suitable.
- Define strk() as a static function in global scope.
This avoids the "nested extern declaration" warnings.
- Use stat

Make WARNS=6 happy with our init(8):
- Use more ``const''s where suitable.
- Define strk() as a static function in global scope.
This avoids the "nested extern declaration" warnings.
- Use static initialization of strings, rather than
referring string constants through char *.
- Bump WARNS from 0 to 6.

NOSHARED -> NO_SHARED

Introduce the PRECIOUSPROG knob in bsd.prog.mk, similar
to PRECIOUSLIB from bsd.lib.mk. The side effect of this
is making installing the world under jail(8) possible by
using another knob, NOFSCHG.

style.Makefile(5):
Use WARNS?= instead of WARNS=.

Make init statically linked by default. It's not worth the pain of having
a dynamically linked init as recently seen by ia64 woes.

Approved by: re (jhb)

Default to WARNS=2.
Binary builds that cannot handle this must explicitly set WARNS=0.

Use new backup feature of install(1).

- Backout botched attempt to introduce MANSECT feature.
- MAN[1-9] -> MAN.

Set the default manual section for sbin/ to 8.

Further tidy up the sbin/init and release builds.

This is not necessarily the correct fix, but at least sbin/init compiles
in a sterile environment like "make release"

Bring in System V run-level patches (turned off by default).
While I'm here, fix some typos in the manpage.

Removed definition of _NEW_VFSCONF. The new vfsconf interface is now
the default.

".if exists(${CURDIR}/../../secure)" rather than testing relative to the
object directory.
