Mounting /dev (much like the RELENG_5 and HEAD versions of release/Makefile do) will also be needed. Note that you should be using the 4.x version of release/Makefile* to start "make release", and use WORLDDIR to point to your /usr/src, something like this: cd /tmp cvs co -rRELENG_4 -l release cd /usr/src/release make -f /tmp/Makefile release ... P.S. Last time I tried it (more than a year ago), it worked.
