Then there's also bootblk.text: not required by bootblk, not installed
and only used with Sun's fakeboot in a target that cannot work:
$ make -n fake
([ -h machine ] || ln -s
/home/kn/src/sys/arch/sparc64/stand/bootblk/../../include machine)
../fakeboot/fakeboot -elf32 <bootblk >/bootblk
../fakeboot/fakeboot -elf32 <bootblk.text >/bootblk.text
ksh(1) explains and a quick demo confirms this:
Input/output redirection
[...]
> file [...] Note that this means the command cmd < foo > foo will
open foo for reading and then truncate it when it opens it for
writing, before cmd gets a chance to actually read foo.
$ cat foo
foo
$ cat < foo > foo
$ du foo
0
NetBSD still has the same Makefile bits; I never had access to fakeboot
and thus can't judge its usefulness (today), but I'm pretty sure the
current target can't work.
Is anyone still using this or can it go?
