![]() ld.bfd requires libraries to be linked in order. libssl requires
libcrypto. libfetch requires libssl. To fix the latter, move fetch
up above tar rather than listing the ssl libraries twice.

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. $FreeBSD$
