- 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.
- 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 all
- rely on dynamic linking.
- 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.
