This is what file reports about Fedora's vmlinuz

vmlinuz-2.6.31.9-174.fc12.ppc64:
ELF 64-bit MSB shared object, 64-bit PowerPC or cisco 7500, version 1 (SYSV), statically linked,
stripped

and this is the vmlinux in linux-2.6.32.2/arch/powerpc/boot

vmlinux:
ELF 64-bit MSB shared object, 64-bit PowerPC or cisco 7500, version 1 (SYSV), statically linked, not
stripped

this is zImage in linux-2.6.32.2/arch/powerpc/boot

zImage: ELF 32-bit MSB executable, PowerPC or cisco 4500, version 1 (SYSV), statically linked, with
unknown capability 0x41000000 = 0x13676e75, with unknown capability 0x10000 = 0xb0402, not stripped

vmlinux seems similar to vmlinuz (just a lot bigger), while zImage looks something else

I've tried make binrpm-pkg but it builds the same big file.
I guess my question really is

How do I tell make to strip vmlinux to install vmlinuz?
Otherwise "make install" runs out of space.
