>Description:

While running in securelevel 2, I tried to load a kernel screensaver module
and was met with an operation not permitted. It took me a minute but I'm
assuming that with securelevel 1 disallowing writing to /dev/kmem I cannot
load modules. I was thinking it might be nice to make that more obvious in
the init(8) manpage.

>How-To-Repeat:

sysctl -w kern.securelevel=1
kldload green_saver

>Fix:

Document the fact that securelevel >= 1 disallows module loading more
explicitly.
