Use colons instead of semi-colons in the default init_path to behave like

57de21f5b6 Changes to support diskless booting on the alpha:
* Make the network code in the bootstrap more chatty (helps debugging)
* Add nfs root stuff to cpu_rootconf(). I also added a check to make sure
  it really was netbooting which allows the use of the same kernel for local
  and network boots.
* Tweak the de driver so that it takes the speed setting from the console
  for the alpha (some PWSs have broken de chipsets). This is the same
  behaviour as NetBSD/alpha.

087d4857e5 Bring the 'new-bus' to the i386. This extensively changes the way the
i386 platform boots, it is no longer ISA-centric, and is fully dynamic.
Most old drivers compile and run without modification via 'compatability
shims' to enable a smoother transition.  eisa, isapnp and pccard* are
not yet using the new resource manager.  Once fully converted, all drivers
will be loadable, including PCI and ISA.

(Some other changes appear to have snuck in, including a port of Soren's
 ATA driver to the Alpha.  Soren, back this out if you need to.)

This is a checkpoint of work-in-progress, but is quite functional.

The bulk of the work was done over the last few years by Doug Rabson and
Garrett Wollman.

304195a177 Fix a number of memory leaks and other memory-related disorders.
Also, unbreak the breakage introduced at the last revision of module.c.
This changes the semantics of mod_searchfile() (and mod_searchmodule())
to make the caller's responsibility freeing the buffer returned. This
is different from other functions in loader's code, and was done as a
fix for kern/9631. If someone wants to revert this to the original
behavior, don't forget to fix kern/9631 in another way.

This should also fix bin/10462, which was introduced as a result of the
first try at kern/9631 (module.c last revision).

755c131c9f Make use of prototypes to silence warnings.
Change include() so it will be able to load files with forth code,
instead of just builtins. Remove #@- from the include section of the
help file, since they don't work in the new version of include, unless
BOOT_FORTH is not defined.

Change bf_run() so it will return the result returned by ficlExec(). Also,
make bf_run() push "interpret" to be executed by ficlExec(), since ficlExec()
doesn't do it by itself. (Things worked previously because nothing
recursed through ficlExec() by the way of bf_run()).

Change/extend comments on builtin behavior.

Search for "interpret" at the end of bf_init(), so /boot/boot.4th can
provide it's own version.

Remove dead code.

bootinfo structure where bi_esymtab < bi_symtab was being passed
to the kernel.  In the case of older 2.x kernels, this was causing

36945c480b This fixes a bug in the bcache code whereby false cache hits occur
the first time block 0 is read. This fix initialises the block
numbers to -1 which isn't the most correct thing for a daddr_t but
it isn't likely to cause a problem in the boot blocks and it could
do with a more thought out fix later.

The bug is probably benign on the i386 but on the alpha it can
cause initial file opens to fail. This is the cause of the "can't
open /boot/boot.conf" errors.

It appears on the alpha because of a number of combining factors.
On the alpha the LABELSECTOR is 0 so block 0 needs to be read in
from the media. The first time this happens you get a false hit
because the bc_blkno field is zero initially. Also, the timestamp
check against this cache hit succeeds because on the alpha a hacked
getsecs() function can return 0 when it starts counting so that
the zero initial timestamp + BCACHE_TIMEOUT is greater than the
current time until getsecs() has counted passed BCACHE_TIMEOUT.

The overall effect is that the first open() that occurs gets a
false cache hit and returns garbage to the bd_strategy() function
which then fails the open() call. This false hit then stays in the
cache until BCACHE_TIMEOUT getsecs() ticks have passed; all open()
calls during this time fail.

This explains why you can generally access the media by the time
you get to interp() and start issuing commands but the earlier
attempts to run the boot scripts are failing.

It's possible that this is causing the problem switching to the
mfsroot floppy as well but I haven't confirmed that.
