The inst_execd script is remarkably large for what it does and is
entirely unnecessary in practice.  The script below does nearly
everything the inst_execd script does (assuming you have a shared
SGE_ROOT) and can be run on any machine with admin privs.  You then just
need to arrange to install an appropriate startup script which runs
${SGE_ROOT}/${SGE_CELL}/common/sgeexecd.  This is was we do on our
netbooted cluster.
