stap-server and systemtap init script include /etc/rc.d/init.d/functions . This file does not exist in all Linux distributions (for example Debian). I don't know what does that file contain, but name looks similar to /lib/lsb/init-functions.

commit 5ac7fee Default functions are now provided in stap-server when /etc/rc.d/init.d/functions does not exist.
commit 52244d5 Default functions are now also provided for initscript/systemtap.
