COMMAND sysinstall SYSTEMS AFFECTED FreeBSD prior to v3.0 PROBLEM Jonas Eriksson posted following. There was an symlink race problem in FreeBSD /stand/sysinstall until FreeBSD version 3.0 When root is reading help-documents in sysinstall it will create an tmp file named doc.tmp in /tmp that anyone could symlink to /etc/passwd for example. SOLUTION FreeBSD 3.0 fixed this.
