>Description:

This may be a documentation bug only, but I can't find a way to
express in boot.cfg the equivalent of these two commands
entered at the boot prompt:

---8<---
fs cgdrd.img
boot netbsd
--->8---

I don't want a menu to display, my naive try was

---8<---
clear
timeout=0
fs cgdrd.img
boot netbsd
--->8---

but that did not work (everything worked fine, but the ramdisk was
not loaded).

Mimicing the "load" syntax from boot.cfg doces did not work either:

fs=cgdrd.img
