This allows writing setup scripts that contain lines starting with
"#!", e.g., a shebang when creating a shell script using cat:
#!/bin/sh
echo "Populate rc.local"
cat >/etc/rc.local<<EOF
#!/bin/sh
echo booted | logger -s -t 'example'
EOF
Prevent accidentally running a setup script left behind by a
previous invocation of bsdinstall.
