V100, the firmware is known to be broken and not allowing to simultaneously
open disk devices, causing attempts to boot from a mirror or RAIDZ to cause
a crash. This will be worked around later. The firmwares of newer sun4u models
don't seem to exhibit this problem though.
Steps for ZFS booting:
1. create VTOC8 label
# gpart create -s vtoc8 da0
2. add partitions, f.e.:
# gpart add -t freebsd-zfs -s 60g da0
# gpart add -t freebsd-swap da0
resulting in something like:
# gpart show
=> 0 143331930 da0 VTOC8 (68G)
0 125821080 1 freebsd-zfs (60G)
125821080 17510850 2 freebsd-swap (8.4G)
3. create zpool
# zpool create bunker da0a
or for mirror/RAIDZ (after preparing additional disks as in steps 1. + 2.):
# zpool create bunker mirror da0a da1a
# zpool create bunker raidz da0a da1a da2a ...
4. set bootfs
# zpool set bootfs=bunker bunker
5. install zfsboot
# zpool export bunker
# gpart bootcode -p /boot/zfsboot da0
6. write zfsloader to the ZFS Boot Block (so far, there's no dedicated tool
for this, so dd(1) has to be used for this purpose)
When using mirror/RAIDZ, step 4. and the dd(1) invocation should be repeated
for the additional disks in order to be able to boot from another disk in
case of failure.
# sysctl kern.geom.debugflags=0x10
# dd if=/boot/zfsloader of=/dev/da0a bs=512 oseek=1024 conv=notrunc
# zpool import bunker
7. install system on ZFS filesystem
Don't forget to set 'zfs_load="YES"' and vfs.root.mountfrom="zfs:bunker" in
loader.conf as well as 'zfs_enable="YES"'in rc.conf.
8. copy zpool.cache to the ZFS filesystem
cp -p /boot/zfs/zpool.cache /bunker/boot/zfs/zpool.cache
9. set mountpoint
# zfs set mountpoint=/ bunker
10. Now, given that aliases for all disks in the zpool exists (check with
the `devalias` command on the boot monitor prompt) and disk0 corresponds
to da0 (likewise for additional disks), the system can be booted from the
ZFS with:
{1} ok boot disk0

code that is used to construct a loader (e.g. libstand, ficl, etc).
There is such a thing as a 64-bit EFI application, but it's not
as standard as 32-bit is. Let's make the 32-bit functional (as in
we can load and actualy boot a kernel) before solving the 64-bit
loader problem.
Before r228267 the option was honored but the original content of
boot.config was not preserved. I tried to fix that but missed the idea.
Now the proper way of doing things is taken from i386/boo2.
Also, a comment is added to explain this a little bit unobvious
behavior.

The menu item is now made completely independent with the ACPI item - most
modern systems seem to require ACPI and become even more "unsafe"
without it.
Safe Mode no longer disables APIC for the same reason.
kbdmux is not disabled as this feature has proven itself stable.
New actions:
- SMP is disabled in the Safe Mode now
- eventtimers are forced to periodic mode (some real and virtual systems
seem to have problems otherwise)
- geom extra vigorous integrity checking is disabled, this is to
facilitate migration from previous versions
Possible short term to do:
- make SMP switch a separate menu item
- restore APIC switch as a separate menu item
Longer term to do:
- turn various tweaks into separate menu items in a Safe Mode sub-menu
Please consider adding a safety tweak to Safe Mode when introducing
new major features or changes that may cause instabilities.

quantum bytewise to the address of a 64-bit variable results in writing
to the "wrong" 32-bit half so adjust the address accordingly. This fix
is implemented in a hackish way for two reasons:
o in order to be able to get it into 8.3 with zero impact on the little-
endian architectures where this bug has no effect and
o to avoid blowing the x86 boot2 out of the water again when compiling
it with clang, which all sane versions of this fix tested do.
This change fixes booting from UFS1 file systems on big-endian machines.

it's value is change to be an empty string after the initial call to
parse, and cmd[]'s value can be changed (thus losing a prior setting for
kname) due to user input at the boot prompt. While here, ensure that that
initial boot config file text is nul-terminated, that ops is initialized
to zero, and that kname is always initialized to a valid string.

- NO_WFORMAT.clang (disables -Wformat and friends)
- CLANG_NO_IAS (disables integrated assembler)
- CLANG_OPT_SMALL (adds flags for extra small size optimizations)
As a side effect, this enables setting CC/CXX/CPP in src.conf instead of

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]

'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.
