1afde994e9 Pass lists of possible root devices and their names up to the
machine-independent code and try mounting the devices in the
lists instead of guessing alternative root devices in a machine-
dependent way.

autoconf.c:
Reject preposterous slice numbers instead of silently converting
them to COMPATIBILITY_SLICE.

Don't forget to force slice = COMPATIBILITY_SLICE in the floppy
device name.

Eliminated most magic numbers and magic device names in setroot().

Fixed dozens of style bugs.

vfs_conf.c:
Put the actual root device name instead of "root_device" in the
mount struct if the actual name is available.  This is useful after
booting with -s.  If it were set in all cases then it could be used
to do mount(8)'s ROOTSLICE_HUNT and fsck(8)'s hotroot guess better.

c0bab11dfe Make the devfs SLICE option a standard type option.
(hopefully it will go away eventually anyhow)

3e425b968d Add changes and code to implement a functional DEVFS.
This code will be turned on with the TWO options
DEVFS and SLICE. (see LINT)
Two labels PRE_DEVFS_SLICE and POST_DEVFS_SLICE will deliniate these changes.

/dev will be automatically mounted by init (thanks phk)
on bootup. See /sys/dev/slice/slice.4 for more info.
All code should act the same without these options enabled.

This code does not support the following:
bad144 handling.
Persistance. (My head is still hurting from the last time we discussed this)
ATAPI flopies are not handled by the SLICE code yet.

When this code is running, all major numbers are arbitrary and COULD
be dynamically assigned. (this is not done, for POLA only)
Minor numbers for disk slices ARE arbitray and dynamically assigned.

617dd81f70 If the root mount fails from a device that is not the compatability slice
of a disk, because that slice does not exist, try again mounting from the
compatability slice.

This handles the case where a disk has been initialised by 'disklabel
auto', which places a bogus and invalid slice entry on the disk.
The bootstrap is not smart enough to reject this slice, and pretends to
boot from it.  Believing the the bootstrap at this point is unwise.

Booting from non-'wd' disks thus prepared is still broken, as
'disklabel -rwB xdN auto' does not initialise the disk type field, and
the bootstrap mistakenly claims that the disk is handled by 'wd'.

Behaviour is now consistent with DEVFS expected characteristics.

95802bf803 Shift a few SYSINT() calls around.
this results in a few functions becoming static, and
the SYSINITs being close to the code they are related to.
setting up the dump device is with dumpsys() and
kicking off the scheduler is with the scheduler.
Mounting root is with the code that does it.

a1c995b626 Last major round (Unless Bruce thinks of somthing :-) of malloc changes.
Distribute all but the most fundamental malloc types.  This time I also
remembered the trick to making things static:  Put "static" in front of
them.

996c772f58 This is the kernel Lite/2 commit. There are some requisite userland
changes, so don't expect to be able to run the kernel as-is (very well)
without the appropriate Lite/2 userland changes.

The system boots and can mount UFS filesystems.

Untested: ext2fs, msdosfs, NFS
Known problems: Incorrect Berkeley ID strings in some files.
		Mount_std mounts will not work until the getfsent
		library routine is changed.

1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

Submitted by:	terry (terry lambert)
This is  a composite of 3 patch sets submitted by terry.
they are:
New low-level init code that supports loadbal modules better
some cleanups in the namei code to help terry in 16-bit character support
some changes to the mount-root code to make it a little more
modular..

NOTE: mounting root off cdrom or NFS MIGHT be broken as I haven't been able
to test those cases..

certainly mounting root of disk still works just fine..
mfs should work but is untested. (tomorrows task)

The low level init stuff includes a total rewrite of init_main.c
to make it possible for new modules to have an init phase by simply
adding an entry to a TEXT_SET (or is it DATA_SET) list. thus a new module can
be added to the kernel without editing any other files other than the
'files' file.

e0e9c42112 Implemented filesystem clean bit via:
machdep.c:
	Changed printf's a little and call vfs_unmountall() if the sync was
	successful.

cd9660_vfsops.c, ffs_vfsops.c, nfs_vfsops.c, lfs_vfsops.c:
	Allow dismount of root FS. It is now disallowed at a higher level.

vfs_conf.c:
	Removed unused rootfs global.

vfs_subr.c:
	Added new routines vfs_unmountall and vfs_unmountroot. Filesystems
	are now dismounted if the machine is properly rebooted.

ffs_vfsops.c:
	Toggle clean bit at the appropriate places. Print warning if an
	unclean FS is mounted.

ffs_vfsops.c, lfs_vfsops.c:
	Fix bug in selecting proper flags for VOP_CLOSE().

vfs_syscalls.c:
	Disallow dismounting root FS via umount syscall.
