The leading part of the image name is dependent
on the type of kernel we are booting.

]> grep KERNEL_IMAGETYPE qemu*
qemuarm.conf:KERNEL_IMAGETYPE = "zImage"
qemumips.conf:KERNEL_IMAGETYPE = "vmlinux"
qemumips-variant.conf:KERNEL_IMAGETYPE = "vmlinux"
qemuppc.conf:KERNEL_IMAGETYPE = "zImage"
qemux86-64.conf:KERNEL_IMAGETYPE = "bzImage"
qemux86.conf:KERNEL_IMAGETYPE = "bzImage"

And those are your differences in the name.

As for why the symlinks may not be created at times, I'm
not sure.

Should be something you can script by checking the
KERNEL_IMAGETYPE.
