If the system was booted with ZFS, a new menu item (#7) appears
It contains an autogenerated list of ZFS Boot Environments
This allows the user to switch to an alternate root file system
Use Cases:
- Revert a failed upgrade
- Concurrently run different versions of FreeBSD with common home directory
- Easier integration with the sysadmin/beadm utility

Thinking this through, and looking at process_assignment, I believe
moving the code would be wrong considering that set_conf_files is
called in one condition while set_nextboot_conf is guarded by a
different condition of having nextboot_enable="YES". So these must
stay separated and not combined.

Fix erroneous error path in error messages when processing boot_conf.
Fixup stack comments for functions introduced by SVN r97201.
Remove a questioning stack comment introduced by SVN r186789.
NB: Comment removed because strdup usage here is correct/not a leak.

This is not properly respecting WITHOUT or ARCH dependencies in target/.
Doing so requires a massive effort to rework targets/ to do so. A
better approach will be to either include the SUBDIR Makefiles directly
and map to DIRDEPS or just dynamically lookup the SUBDIR. These lose
the benefit of having a userland/lib, userland/libexec, etc, though and
results in a massive package. The current implementation of targets/ is
very unmaintainable.
Currently rescue/rescue and sys/modules are still not connected.

a text file with a list of physical memory addresses to exclude, and have it
loaded at boot time via the provided example in loader.conf. The tunable
'vm.blacklist' remains, but using an external file means that there's no
practical limit to the size of the list. This change also improves the
scanning algorithm for processing the list, scanning the list only once
instead of scanning it for every page in the system. Both the sysctl and
the file can be unsorted and contain duplicates so long as each entry is
numeric (decimal or hex) and is separated by a space, comma, or newline
character. The sysctl 'vm.page_blacklist' is now provided to report what
memory locations were successfully excluded.

earlier migration away from sloppy mode-endings (r280925,280974-280976)

NB: This deeply effected HardenedBSD which had a default value set.
Embarassingly, I allowed the `type' primitive to be passed -1/-1 for
c-addr/u stack input (the effect of which is to pull INT_MAX bytes
from character address negative one in which hilarity ensues over a
black screen in full-on bootlock). Much thanks to Shawn Webb [lattera]
for helping me diagnose.
NB: The mode-ending revisions were initially suspected (and reverted)
but proved to be a red-herring. Proper mode endings will be returning.

Test Plan:
Drop a head copy of check-password.4th into /boot and then apply the patch
(only the patch to /boot/check-password.4th is required; no other changes are
required but you do have to have a HEAD copy of check-password.4th to
apply the patch).
NB: The rest of your /boot files can be up to 2 years old but no older.
NB: The test won't work unless your kernel has the following change
https://svnweb.freebsd.org/base?view=revision&revision=273489
Now, put into /boot/loader.conf:
geom_eli_passphrase_prompt="YES"
and reboot.
You should be prompted for a GELI passphrase before the menu (if enabled),
just after loading loader.conf(5).
NB: It doesn't matter if you're using GELI or not. However if you are using
GELI and a sufficiently new enough release (has SVN r273489) and you entered
the proper passphrase to mount your GELI encrypted root device(s), you should
notice that the boot process did not stop (you went from loader all the way to login).
