We generally document shutdown(8) instead of reboot(8) as it's better for
interactive use.
In modern FreeBSD is matters a lot less, it's mostly just convention. One
minor thing is that shutdown(8) produces a global message, while reboot(8)
does not. It is believed that historically, some versions of reboot did not
do appropriate safe shutdown checks and just rebooted.
It's also just consistency: for example the handbook[1] documents shutdown.
There is actually another important difference between reboot and shutdown
-r now: reboot does not run /etc/rc.shutdown. This is because reboot has
its own shutdown procedure and does not signal init like init 6 and
shutdown -r now do (except in the case of rerooting via reboot -r).
A few years ago jilles@ proposed changing reboot's default to signalling
init (preserving reboot -q which just invokes the reboot system call), but
this was not accepted. Perhaps this can be tried again for 13.0.

Now it can be used to effectively "build in a subdir". It will use the
'cross-tools', 'libraries', and 'includes' phases of 'buildworld' to properly
setup a WORLDTMP to use. Then it will build 'everything' only in the
listed SUBDIR_OVERRIDE directories. It is still required to list custom
library directories in LOCAL_LIB_DIRS if SUBDIR_OVERRIDE is something
that contains libraries outside of the normal area (such as
SUBDIR_OVERRIDE=contrib/ofed needing LOCAL_LIB_DIRS=contrib/ofed/usr.lib)
Without these changes, SUBDIR_OVERRIDE with buildworld was broken or hit
obscure failures due to missing libraries, includes, or cross compiler.
SUBDIR_OVERRIDE with 'make <target that is not buildworld>' will continue to
work as it did before although its usefulness is questionable.
With a fully populated WORLDTMP, building with a SUBDIR_OVERRIDE with
-DNO_CLEAN only takes a few minutes to start building the target
directories. This is still much better than building unneeded things via
'everything' when testing small subset changes. A BUILDFAST or
SKIPWORLDTMP might make sense for this as well.
- Add in '_worldtmp' as we still need to create WORLDTMP as later targets,
such as '_libraries' and '_includes' use it. This probably was avoiding
calling '_worldtmp' to not remove WORLDTMP for debugging purposes, but
-DNO_CLEAN can be used for that.
- '_legacy' must be included since '_build-tools' uses -legacy.
The SUBDIR_OVERRIDE change came in r95509, while -legacy being part
of build-tools came in r113136.
- 'bootstrap-tools' is still skipped as this feature is not for
upgrades.
- Fix buildworld combined with SUBDIR_OVERRIDE not installing all includes.
The original change for SUBDIR_OVERRIDE in r95509 kept '_includes'
and '_libraries' as building everything possible as the SUBDIR_OVERRIDE
could need anything from them. However in r96462 the real 'includes'
target was changed from manual sub-makes to just recursing 'includes'
on SUBDIR, thus not all includes have been installed into WORLDTMP since then
when combined with 'buildworld'.
This is not done unless calling 'make buildworld' as it would be
unexpected to have it go into all directories when doing 'make
SUBDIR_OVERRIDE=mydir includes'.
- Also need to build the cross-compiler so it is used with --sysroot.
If this is burdensome then telling the build to use the local compiler
as an external compiler (thus using a proper --sysroot to WORLDTMP) is
possible by setting CC=/usr/bin/cc, CXX=/usr/bin/c++, etc.
- Don't build the lib32 distribution with SUBDIR_OVERRIDE in buildworld
since it won't contain anything related to SUBDIR_OVERRIDE. Testing
of the lib32 build can be done with 'make build32'.
- Document these changes in build.7
