 1.18  19-Sep-2020  thorpej Enable MULTIPROCESSOR by default, but disable it in the RAMDISK
and INSTALL kernels to save some space.
 1.17  06-Feb-2009  jym Changes to MEMORY_RBFLAGS option:
- renamed to MEMORY_DISK_RBFLAGS to better fit the rest of the
MEMORY_DISK options(4)
- change default value to RB_AUTOBOOT instead of RB_SINGLE, and adapt
the config(5) files accordingly
- document this option inside options(4)

Rename MEMORY_DISK_SIZE (formerly MINIROOTSIZE) to MEMORY_DISK_ROOT_SIZE,
which was suggested by Izumi Tsutsui <tsutsui@ceres.dti.ne.jp> as
being more consistent with what it's controlling...
 1.15  10-Mar-2002  lukem * rename MINIROOTSIZE to MEMORY_DISK_SIZE, so that all md(4) options
are now consistently named
* fold opt_mdsize.h into opt_md.h
 1.14  24-Aug-1997  cgd branches: 1.14.30; 1.14.32;
fix spaces/tabs lossage: if we're going to do "options<space><tab>", be
consistent about it (fix it in all files)! Also, there's no point at all
in doing "file-system<space><tab>", so kill the spaces.
 1.13  06-Apr-1997  cgd branches: 1.13.4;
clean up NetBSD RCS ID strings
 1.12  24-Feb-1997  leo Force root to be on the ram-disk.
 1.11  14-Jan-1997  cgd branches: 1.11.4;
useful suggestion from jason: make this simply an 'include' of the
GENERIC kernel config with the added ramdisk-hook-enabling bits!
 1.10  28-Dec-1996  pk branches: 1.10.2;
rename: ramdisk => md
 1.9  03-Dec-1996  cgd branches: 1.9.2;
clean up SCSI devices
 1.8  26-Nov-1996  cgd add a comment re: eb164
 1.7  25-Nov-1996  cgd update for recent configuration changes.
 1.6  19-Nov-1996  cgd update for VGA changes, and clean up slightly.
 1.5  15-Nov-1996  cgd move DEVPAGER, SWAPPAGER, VNODEPAGER options into std.alpha since they're
mandatory, and clean up their descriptions.
 1.4  03-Oct-1996  cgd switch to 'swap generic' since that works now (minimal diffs from GENERIC)
 1.3  27-Sep-1996  cgd update for changes to config.
 1.2  16-Sep-1996  cgd add EISAVERBOSE, TCVERBOSE as appropriate. Add UCONSOLE to all.
slight cleanup + sync.
 1.1  15-Sep-1996  cgd like GENERIC, but uses built-in ramdisk image for root
 1.9.2.2  01-Jun-1997  cgd sync the nwscons branch up with yesterday's version of the trunk.
Lots of conflicts/changes because of the RCS Id format changes.
Also, a few cleanups and corrections.
 1.9.2.1  24-Jan-1997  cgd sync with trunk
 1.10.2.3  30-Jan-1997  thorpej update from trunk

 1.10.2.1  14-Jan-1997  thorpej Snapshot of work-in-progress, committed to private branch.

These changes implement machine-independent root device and file system
selection. Notable features:

- All ports behave in a consistent manner regarding root
device selection.
- No more "options GENERIC"; all kernels have the ability
to boot with RB_ASKNAME to select root device and file system
type.
- Root file system type can be wildcarded; a machine-independent
function will try all possible file systems for the selected
root device until one succeeds.
- If the root file system fails to mount, the operator will
be given the chance to select a new root device and file
system type, rather than having the machine simply panic.
- nfs_mountroot() no longer panics if any part of the NFS
mount process fails; it now returns an error, giving the
operator a chance to recover.
- New, more consistent, config(8) grammar. The constructs:

config netbsd swap generic
config netbsd root on nfs

have been replaced with:

config netbsd root on ? type ?
config netbsd root on ? type nfs

Additionally, the operator may select or wildcard root file
system type in the kernel configuration file:

config netbsd root on cd0a type cd9660

config(8) now requires that a "root" specification be
made. "root" may be wired down or wildcarded. "swap" and
"dump" specifications are optional, and follow previous
semantics.

- config(8) has a new "file-system" keyword, used to configure
file systems into the kernel. Eventually, this will be used
to generate the default vfssw[].

- "options NFSCLIENT" is obsolete, and is replaced by
"file-system NFS". "options NFSSERVER" still exists, since
NFS server support is independent of the NFS file system
client.

- sys/arch/<foo>/<foo>/swapgeneric.c is no longer used, and
will be removed; all information is now generated by config(8).

As of this commit, all ports except arm32 have been updated to use
the new setroot(). Only SPARC, i386, and Alpha ports have been
tested at this time. Port masters should test these changes on their
ports, and report any problems back to me.

More changes are on their way, including RB_ASKNAME support in
nfs_mountroot() (to prompt for server address and path) and, potentially,
the ability to select rarp/bootparam or bootp in nfs_mountroot().
