yes true. grub can boot openbsd indirectly, but not directly
like the doco claims it can. the grub doco gives instructions
for booting netbsd and openbsd directly but those instructions
don't work (and haven't for 5 years, apparently). it would be
nice for the doco to be updated to contain valid instructions
such as the following.
