I just stumbled upon this page, which says that bzImage and vmlinuz are identical.
bzImage is then copied using the cp (i.e., copy) command to the /boot directory and simultaneously renamed vmlinuz with a command such as
cp /usr/src/linux/arch/i386/linux/boot/bzImage /boot/vmlinuz
This is worrying me, as up to now my understanding was as follows:
vmlinux: Plain linux ELF file just the way it was created by the linker, including symbols and everything.
vmlinuxfile which got stripped of all its symbols
zImage: bootsect.o + setup.o + misc.o + piggy.o (piggy.o contains the piggy-backed
zImageis bootable because it can decompress and run the kernel it contains.
bzImage: same as
zImageexcept that it is built slightly differently which enables it to carry bigger kernels.
Can you tell me who is correct?
