>Description:

Noticed during pkg builds: executing shell scripts w/o a #! interpreter
line as first line triggers a (harmless) kernel diagnostic. This is
only a cosmetic problem.

>How-To-Repeat:

echo "echo yay" > demo.sh
chmod u+x demo.sh
./demo.sh
dmesg | tail

(or look at console output)

execve_loadvm: check exec failed for ./demo.sh, error 8


>Fix:
n/a
