from the interactive loader(8) prompt and beastie_disable="YES" is set
in loader.conf(5). In this case menu.rc is not evaluated and consequently
menu-unset does not have a body yet. This results in the ficl warning
"menu-unset not found" when try-menu-unset invokes menu-unset.
Check for beastie_disable="YES" explicitly, so that the try-menu-unset
word will not attempt to invoke menu-unset because the menu will have
never been configured. [1]
Use the sfind primitive as a last resort as an additional safer approach
conjuring a foreign word safely. [2]

'comconsole_pcidev'. The former allows to set the base address of the
serial console i/o port. The later takes the string of the format
'bus:device:function:[bar]' as a value and uses the serial port attached
as PCI device at the specified location for console.
Both variants pass 'hw.uart.console' variable to the uart driver to
properly hand-over the kernel console.
Change allows to use ISA serial ports other than COM1 for the
loader/kernel console without loader recompilation. Also, you can use
PCI-attached port as the console, e.g. Intel AMT serial pseudo-port on
some motherboards based on Q67 chipset.

The index() and rindex() functions were marked LEGACY in the 2001
revision of POSIX and were subsequently removed from the 2008 revision.
The strchr() and strrchr() functions are part of the C standard.
This makes the source code a lot more consistent, as most of these C
files also call into other str*() routines. In fact, about a dozen
already perform strchr() calls.
As I looked through the C library, I noticed the FreeBSD MIPS port has a
hand-written version of index(). This is nice, if it weren't for the
fact that most applications call strchr() instead.
Also, on the other architectures index() and strchr() are identical,
meaning we have two identical pieces of code in the C library and
statically linked applications.
Solve this by naming the actual file strchr.[cS] and let it use
__strong_reference()/STRONG_ALIAS() to provide the index() routine. Do
the same for rindex()/strrchr().
This seems to make the C libraries and static binaries slightly smaller,
but this reduction in size seems negligible.
before invoking the kernel.
Quoting submitter:
The issue is with the new boot loader menu. It adds many loader variables
including ones that contain ANSI color escapes.
Obviously, these ANSI codes don't play well with serial consoles when
kenv(1) is executed without arguments (reports vary as to what happens,
but it's never pretty).
The net-effect is that kenv(1) no longer reports menu-related variables.
In essence, kenv(1) output should now appear the same as on RELENG_8
(which lacks the new boot loader and didn't use any such variables).
Thus, restoring serial console glory.

In an example of boot command:
- rename wd(4) IDE disk drives name to ad(4) for the time being.
- update the used kernel path "/kernel" to the current default.
[It still worked occasionally by looking into the /boot/kernel directory,
so the resulting path was "/boot//kernel/kernel", with two slashes.]

At work, where we use use KVM+QEMU, we notice that pxeboot is pratically
impossible because of network timeouts. This is due to the fact that the
RTC code makes aggressive jumps.
Two RTC reads does not seem to be sufficient. Change the code to check

- Use this header instead of magic numbers and various duplicate structure
definitions for doing I/O.
- Use an actual structure for the request to fetch drive parameters in
drvsize() rather than a gross hack of a char array with some magic
size. While here, change drvsize() to only pass the 1.1 version of
the structure and not request device path information. If we want
device path information you have to set the length of the device
path information as an input (along with probably checking the actual
EDD version to see which size one should use as the device path
information is variable-length). This fixes data smashing problems
from passing an EDD 3 structure to BIOSes supporting EDD 4.

gpt and zfs boot blocks are not nearly as size-constrained as boot2
from which they inherited their current optimization and anti-optimization
options. As such the current options do not provide any benefit, but
make debugging of the code much harder.
Also, it has been demonstrated that combination of -mrtd and
-fno-unit-at-a-time may result in mis-compilation of the boot code
with the current base gcc.
Additionally, intermediate assembly file filtering is removed for
zfsboot.
The new boot blocks are all compile- and boot- tested using qemu.
gptzfsboot is tested with real hardware.
