920dff4b7c If /dev/constty exists, use it instead of /dev/console for single user shell. 
I'm not 100% certain it should call login_tty() for anything else.

58915e2274 If /dev/MAKEDEV is a symlink then preserve the symlink in the mfs /dev. 
If /dev/MAKEDEV doesn't exist then try to run /etc/MAKEDEV instead.
Use the (new) '-n inodes' option to mount_mfs and base the size on the number
of inodes and the size of the MAKEDEV script.

b96069c077 Always compile in support for attempting to obtain the major device 
number of the console from sysctl("machdep.console_device"), rather
than making in optional on the (unused) #ifdef DEBUG.
Certain platforms do not have the console at makedev(0,0) (including
many arm32 and some sh3 platforms), so the "mfs MAKEDEV" hack would
have failed on those.

Noted in private discussion with Quentin Barnes.

c48a08886b Rename MSDOSFS_ROOT to MFS_DEV_IF_NO_CONSOLE, and rework: 
- Always attempt mfs dev if missing /dev/console
    - Save and run both MAKEDEV and MAKEDEV.local
    - After creating the mfs dev, mknod() and freopen() /dev/console.
    - If MAKEDEV is missing do not fail out early, but still create the mfs,
      /dev/console.
    - If we hit any errors fail out to single user.
This change _only_ affects systems booting without /dev/console.

efcc9a4c9d * Add user-controlled mk.conf variables 
- SHLIBDIR	Location to install shared libraries if ${USE_SHLIBDIR}
			is "yes".  Defaults to "/usr/lib".

	- USE_SHLIBDIR	If "yes", install shared libraries in ${SHLIBDIR}
			instead of ${LIBDIR}.  Defaults to "no".
			Sets ${_LIBSODIR} to the appropriate value.
			This may be set by individual Makefiles as well.

	- SHLINKDIR	Location of shared linker.  Defaults to "/usr/libexec".
			If != "/usr/libexec", change the dynamic-linker
			encoded in shared programs

* Set USE_SHLIBDIR for libraries used by /bin and /sbin:
	libc libcrypt libcrypto libedit libipsec libkvm libm libmi387
	libtermcap libutil libz

* If ${_LIBSODIR} != ${LIBDIR}, add symlinks from ${LIBDIR}/${LIB}.so*
  to ${_LIBSODIR}/${LIB}.so* for compatibility.

* Always install /sbin/init statically (for now)


The net effect of these changes depends on how the variables are set:

  1.)	If nothing is set or changed, there is no change from the
	current behaviour:
		- Static /bin, /sbin, and bits of /usr/*
		- Dynamic rest
		- Shared linker is /usr/libexec/ld*so

  2.)	If the following make variables are set:
		LDSTATIC=
		SHLINKDIR=/lib
		SHLIBDIR=/lib
	Then the behaviour becomes:
		- Dynamic tools
		- .so libraries used by /bin and /sbin are installed to /lib,
		  with symlinks from /usr/lib/lib*so to -> /lib/lib*so
		  where appropriate
		- Shared linker is /lib/ld*so

  3.)	As per 2.), but add the following variable:
		USE_SHLIBDIR=yes
	This forces all .so's to be instaleld in /lib (with compat
	symlinks), not just those tagged by their Makefiles to be.
	Again, compat symlinks are installed

53222a55ef 1) change rcsid[] and copyright[] to use __RCSID and __COPYRIGHT 
macros.
2) Clean up some gratuitous uses of write() instead of fprintf()
3) Clean up some of the alternative shell code in single_user(),
   fixing a couple of bugs in the meanwhile. Also, fix pr-2620 from
   Chris Demetriou -- when an alternative shell is exec'ed, it is now
   not called "-sh" automatically.
4) rename the DEBUGSHELL option ALTSHELL since its almost always used
   in NetBSD.

Notes:
1) It isn't clear that the ALTSHELL code is really ever very useful,
   but we seem to have decided to always enable it anyway.
2) The code in init really needs an overall cleanup, but I just don't
   have time or energy.
