That was the first thing I though about. Unfortunately, /usr/obj/usr/src on beast is not around, because /root/buildworld.sh does the following: rm -rf world* build* /usr/obj/`/bin/pwd` tcsh -c 'time make -s buildworld' > /usr/src/world.log 2>&1 Since /bin/rm is dynamically linked, it succeeded in removing /usr/obj/usr/src. Then make(1) failed right away: $ cat /usr/src/world.log Segmentation fault (core dumped) 0.000u 0.005s 0:00.00 0.0% 0+0k 0+0io 0pf+0w My sincere sympathies to Ken.
