buildroot - Make a "dogfood" option
- Busybox is now capable of replacing most gnu packages for real world use,
- such as developing software or in a live CD. A system built from busybox
- (1.00 with updated sort.c), uclibc 0.9.27, gcc, binutils, make, and a few
- other development tools (http://www.landley.net/code/firmware has an example
- system using autoconf, automake, bison, flex, libtools, m4, zlib,
- and groff: dunno what subset of that is actually necessary) is capable of
- rebuilding itself, from scratch, under itself.
+ Busybox 1.1 will be capable of replacing most gnu packages for real world use,
+ such as developing software or in a live CD. It needs wider testing.
+
+ Busybox should now be able to replace bzip2, coreutils, e2fsprogs, file,
+ findutils, gawk, grep, inetutils, less, modutils, net-tools, patch, procps,
+ sed, shadow, sysklogd, sysvinit, tar, util-linux, and vim. The resulting
+ system should be self-hosting (I.E. able to rebuild itself from source code).
+ This means it would need (at least) binutils, gcc, and make, or equivalents.
It would be a good "eating our own dogfood" test if buildroot had the option
- of using busybox instead of bzip2, coreutils, file, findutils, gawk, grep,
- inetutils, modutils, net-tools, procps, sed, shadow, sysklogd, sysvinit, tar,
- util-linux, and vim. Anything that's wrong with the resulting system, we
- can fix. (It would be nice to be able to upgrade busybox to be able to
- replace bash, diffutils, gzip, less, and patch as well.)
+ of using a "make allyesconfig" busybox instead of the all of the above
+ packages. Anything that's wrong with the resulting system, we can fix. (It
+ would be nice to be able to upgrade busybox to be able to replace bash and
+ diffutils as well, but we're not there yet.)

+ One example of an existing system that does this already is Firmware Linux:
