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 Tim P.S.

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. *** /dev/null Wed Jan 8 20:22:00 2003 --- rescue/Makefile Wed Jan 8 18:41:52 2003 *************** *** 0 **** --- 1,3 ---- + SUBDIR=librescue rescue + + .include <bsd.subdir.mk> *** /dev/null Wed Jan 8 20:22:00 2003 --- rescue/librescue/Makefile Wed Jan 8 20:10:34 2003 *************** *** 0 **** --- 1,34 ---- + # + # $FreeBSD: src/rescue/librescue/Makefile,v Exp $ + # + + # Certain library entries have hard-coded references to + # /bin, /sbin, etc, that require those entries to be + # recompiled for use in /rescue.
