That would be a great service to be able to use.

Alas, Smoothwall isn't there yet; it doesn't use packages. Maybe some day. Regardless, I still have to manually update the build process when bumping gcc, glibc, binutils and similar utilities; LFS is a good guide, but it still takes a long time to figure out how to make those packages build. Never mind poring through the build logs to find which packages ignore "-m32 -march=i586" (there are plenty of x86 CPUs in use that don't have the CMOV instructions, thus i586 is required). And never mind finding all of a package's dependencies, and adding new ones to the build.
