at runtime and to support distributing additional kernels:
o remove kernel from the base tarball
o add new kernel tarballs
o build + package both SMP and GENERIC kernels when an <arch>/conf/SMP
config file is present
o add sysinstall support for multiple kernels
o update sysinstall to probe for the number of cpus on a system
and auto-select smp/up kernel accordingly
o add a post-kernels install hook to fixup /boot/kernel
o add -ldevinfo to boot crunch for sysinstall's cpu probing logic
Notes:
1. On HEAD this code is not currently used because GENERIC kernels
include SMP. This work is mainly intended for RELENG_6 where the
GENERIC kernel is UP. If HEAD changes to match then just enable
WITH_SMP in sysinstall/Makefile.
2. The cpu probing support is done with acpi and MPTable; this means
some systems will require work for auto-detection to work.
3. The handling of /boot/kernel may need to be revisited; for now
we rename one kernel at the last moment (SMP if installed, otherwise
GENERIC). There are other, possibly better, approaches.
Lots of help from ru, emaste, scottl, and jhb.
this now compiles on i386 with WARNS?= 3. Most of the fixes included
adding missing 'static' keywords to internal functions, using fully-defined
terminators in statically defined arrays of structs, and various
signed vs unsigned mismatches. Also G/C'd unused configSecurity()
function.

- If we are running as init, popup the country menu before the main menu.
If a non-default country is chosen, then a second menu is brought up
to let the user choose a keymap. By default the default keymap for
the country that was selected is highlighted. If the user chooses the
default country, then the default keymap is just assumed and the user
is not presented with the keymap menu. Currently the default country
is set to "United States" except for PC98 which assumes "Japan".

For example, you can dynamically generate and load configuration file
depending on the hardware configuration with the following template:
mediaSetCDROM
mediaOpen
command='/dist/rescue/sh /dist/scripts/install.sh'
system
mediaClose
configFile=/tmp/generated.cfg
loadConfig
Now we have full access to files on the media before installation begins.

1. Provide larger /, /var, and /tmp partitions (the last increase was
in 2001, and we now have both larger hard drives and more space-hungry
software.)
2. If there is enough space available, allocate extra space to /var
sufficient to store a crash dump.
On systems where harddrivesize > 3 * RAMsize + 10GB, the default sizes
will now be as follows:
swap RAMsize * 2
/ 512 MB
/tmp 512 MB
/var 1024 MB + RAMsize
/usr the rest (8GB or more)
On systems where harddrivesize > RAMsize / 8 + 2 GB, the default sizes
will be in the following ranges, with space allocated proportionally:
swap RAMsize / 8 -- RAMsize * 2
/ 256 MB -- 512 MB
/tmp 128 MB -- 512 MB
/var 128 MB -- 1024 MB
/usr 1536 MB -- 8192 MB
On systems with even less disk space, the existing behaviour is not
changed.

(or once people stop arguing about colours of paint)
it is running during installations. The vsystem() function does get
used after this happens (e.g. if you manually configure the network
interface and ask it to enable the interface) so it needs to be a
little smarter about whether it uses /stand/sh or /bin/sh.

the NTP server list.
The servers are by Internet Multifeed Co., and connected to their
IX service JPNAP. It would be a good NTP server for machines in Japan.

with EBUSY and a cdrom is not mounted at /cdrom, sysinstall fails to
treat it as an error and thinks that the disk mounted ok. However, it
doesn't find a cdrom.inf file so it complains. Later when it tries to
unmount the disk due to a mediaClose() umount(2) returns an error, and it
never clears its internal mounted flag. The fix here is to properly
handle EBUSY as an error if there isn't a CD already mounted at /cdrom.
- Add a new CDROMInitQuiet variable that can be used to shut up the dialog
box about the mount(2) system call failing when trying to mount a CD-ROM.
This is used by the feature described below.
- When using a fixit CD, first try to see if we can mount the disc in the
drive now and use it as a fixit CD. If not, then prompt the user to
insert the disc and try again. If we do succeed on the first "silent"
probe then we don't ask the user to eject the disk after leaving fixit
mode.
- Add a simple file existence test to make sure that the disc that we mount
really is a livefs disc.
- Explicitly switch back to ttyv0 when using the standard console after
the fixit shell dies. Previously this behavior worked accidentally
because all the fixit modes popped up a dialog box which contained a
hidden switch to ttyv0.
