Warner suggested:
Also, be sure to post a diff for review prior to commit.
So, here it is. /rescue contains
most of /bin and /sbin, along with a few choice
selections from /usr/bin and /usr/sbin. All
are statically linked and compiled to occupy
a minimum of disk space (About 4MB).
For those who missed some earlier threads, this
is a step towards a fully dynamic FreeBSD.
The next step is to create /lib and move certain
critical shared libs there, then /bin and /sbin
can be switched to fully dynamic linking. Once
that's done, the door is open to use dlopen() within
the standard libraries, which should simplify
pam, nsswitch, locales, and probably a few other
things.
But first, /rescue. There are no doubt a few
refinements that could be made, but this seems
good enough to start using. I'm also in dire need
of a reality check; I've been working on this solo
for too long. ;-)
Note that 'proper' building requires first
applying patches, then updating some tools:
cd /usr/src/share/mk && make install
cd /usr/src/include && make install
cd /usr/src/usr.sbin/crunch && make && make install
You can then build /rescue itself:
mkdir /rescue
cd /usr/src/rescue && make obj && make && make install

entirely sure how to include new files in a diff.

+ The /rescue build system here has three goals:
+
+ 1) Produce a reliable standalone set of /rescue tools.
+
+ The contents of /rescue are all statically linked and do not depend on
+ anything in /bin or /sbin. In particular, they'll continue to
+ function even if you've hosed your dynamic /bin and /sbin. For
+ example, note that /rescue/mount runs /rescue/mount_nfs and not
+ /sbin/mount_nfs. This is more subtle than it looks.
+
+ As an added bonus, /rescue is fairly small (thanks to crunchgen) and
+ includes a number of tools (such as gzip, bzip2, vi) that are not
+ normally found in /bin and /sbin.
+
+ 2) Demonstrate robust use of crunchgen.
+
+ These Makefiles recompile each of the crunchgen components and include
+ support for overriding specific library entries. Such techniques
+ should be useful elsewhere. For example, boot floppies could use this
+ to conditionally compile out features to reduce executable size.
+
+ 3) Produce a toolkit suitable for small distributions.
+
+ Install /rescue on a CD or CompactFlash disk, and symlink /bin and
+ /sbin to /rescue to produce a small and fairly complete FreeBSD
+ system.
+
+ These tools have one big disadvantage: being statically linked, they
+ cannot use some advanced library functions that rely on dynamic
+ linking. In particular, nsswitch, locales, and pam are likely to all
+ rely on dynamic linking in the near future.
+
+
+ To compile:
+
+ # cd /usr/src/rescue
+ # make obj
+ # make
+ # make install
+
+ Note that rebuilds don't always work correctly; if you run into
+ trouble, try 'make clean' before recompiling.
