>Description:
Using anita to install NetBSD 10.99.14 in a VM, I get the following
error messages when trying to locate a kernel:

        ...
        Option 1 will be chosen in   0 seconds.
        read header short
        open netbsd: No such file or directory
        boot: cd0a:netbsd: No such file or directory
        open netbsd.gz/kernel: No such file or directory
        open netbsd.gz: No such file or directory
        boot: cd0a:netbsd.gz: No such file or directory
        open onetbsd/kernel: No such file or directory
        open onetbsd: No such file or directory
        boot: cd0a:onetbsd: No such file or directory
        open onetbsd.gz/kernel: No such file or directory
        open onetbsd.gz: No such file or directory
        boot: cd0a:onetbsd.gz: No such file or directory
        open netbsd.old/kernel: No such file or directory
        open netbsd.old: No such file or directory
        boot: cd0a:netbsd.old: No such file or directory
        open netbsd.old.gz/kernel: No such file or directory
        open netbsd.old.gz: No such file or directory
        boot: cd0a:netbsd.old.gz: No such file or directory

and then it goes back to the boot menu.  After the default timeout,
it tried again to select the default, and loops forever.

Seems like it's processing a list of potential default kernels,
so I added

        { "netbsd/kernel", "netbsd/kernel.gz" }

to the list of kernel names in both efiboot/boot.c and boot/boot2.c
with the hope that boot-time filesystem support includes descending
into (sub)directories.  Alas, it seems that that doesn't work;  I
getthe following additional error messages for the new table entry:

        ...
        open netbsd/kernel/kernel: No such file or directory
        read header short
        boot: cd0a:netbsd/kernel: Inappropriate file type or format
        open netbsd/kernel.gz/kernel: No such file or directory
        open netbsd/kernel.gz: No such file or directory
        boot: cd0a:netbsd/kernel.gz: No such file or directory

	
>How-To-Repeat:
see above
	
>Fix:
	
Presumably we need to teach the boot code about filename paths and
how to descend into a sub-directory?
