- Change the 'fopen' keyword to accept a mode parameter. Note that this
will break existing 4th scripts that use fopen. Thus, the loader
version has been bumped and loader.4th has been changed to check for a
sufficient version on i386 and alpha. Be sure that you either do a full
world build or install or full build and install of sys/boot after this
since loader.old won't work with the new 4th files and vice versa.

On OFW based machines, it is just too confusing having the firmware and
OS loader giving the same prompt. This is a nice compromise that 99% of the
users on non-OFW platforms will probably not even notice.

especially happen when a version of awk that doesn't support POSIX
character classes is used.

value. Perhaps this was intended to be a debugging printf?
information. The default limits only effect machines with > 1GB of ram
and can be overriden with two new kernel conf variables VM_SWZONE_SIZE_MAX
and VM_BCACHE_SIZE_MAX, or with loader variables kern.maxswzone and
kern.maxbcache. This has the effect of leaving more KVM available for
sizing NMBCLUSTERS and 'maxusers' and should avoid tripups where a sysad
adds memory to a machine and then sees the kernel panic on boot due to
running out of KVM.
Also change the default swap-meta auto-sizing calculation to allocate half
of what it was previously allocating. The prior defaults were way too high.
Note that we cannot afford to run out of swap-meta structures so we still
stay somewhat conservative here.
file is processed by passing its name in argv[1]:
return(mod_loadobj(typestr, argv[1]));
however, it is not tested to see if argv[1] actually is defined.
At best, mod_loadobj() near line 244 returns an error like
"can't find 'garbage'" but if the "filename" entered is sufficiently
long, some buffer gets overrun. Of course, "load -t filename" is
actually a typo because we meant to type "load -t mfs_root filename";
nevertheless, a hung machine seems like too harsh a punishment for
such a small typo...

As of this patchset, the loader builds (under NetBSD/macppc), boots, interacts
and talks to BOOTP/NFS servers.

gets the name from the environment variable kernelname, which is set
when a kernel is loaded. For this reason, autoboot will _first_ try
to load a kernel, and only proceed with the wait prompt after that
succeeds. If it fails, it will abort immediately.
While I understand some may think this behavior undesirable, I think
it is, overall, the best thing to do, even if we do not consider the
aesthetic issue. Notice that anyone using the default loader.rc
already has the kernel loaded before autoboot.
On unload, unset kernelname.
Separate the code that tries to load a kernel from the list of options
to the function loadakernel(). It is used by both boot() and
autoboot().
