Description David Woodhouse 2007-04-07 23:12:08 UTC
Petitboot is a kexec-based bootloader intended primarily for use on PlayStation
3, where we put a kernel+initrd into flash to act as a bootloader.

In such a system we need a very minimal busybox, using something like the
attached config. Please could we build a 'busybox-petitboot' subpackage for it,
just like we do for the 'busybox-anaconda' subpackage?

Comment 2 David Woodhouse 2007-04-07 23:22:07 UTC
It seems that the addition of -lsepol to $(cmd_link) in Rules.mak, which is done
by busybox-1.2.0-selinux.patch, isn't actually needed. It gets added to
$(LIBRARIES) anyway. Removing that makes the minimal busybox.petitboot no longer
link against libsepol -- while the other two builds do still link against it

Having done that, we can remove busybox-1.2.0-gcc41.patch entirely -- it doesn't
do anything except add a single space on the line previously modified by the
selinux patch.

I think you have to turn off CONFIG_BUILD_AT_ONCE (in busybox-petitboot.config)
because it fails otherwise. It would save about 30KiB though, so I'll look into
fixing it at some point.
