The good news is that all four packages - sysklogd, netkit-telnet, e2fsprogs, and pax - build and install correctly straight from the tarball with no patches when dropped into /usr/src/lsbsi-intermediate with /usr/src/lsbsi mounted in a target directory; it would be trivial to add xml for them to the phase4 build. (FYI, I only attempt make; make install in the netkit-telnet/telnetd subdirectory).
My experience with trying to build these with lsbcc - i.e. as conforming apps - was nowhere near as positive. At the moment I think I'd vote for ease-of-use over conceptual purity (i.e., putting them in the appbat)
