No, it (checking the total size of the binary) is by design. - a kernel binary is loaded by a Linux kernel module (named zbsdmod.o) on the native Zaurus Linux - to load a NetBSD kernel, the whole binary is copied into /proc/zboot node, created by the zbsdmod.o module - zbsdmod.o has 5MB buffers to store a copied kernel binary - zbsdmod.o reads a kernel from the 5MB buffer and loads sections into the target addresses https://nxr.netbsd.org/xref/src/sys/arch/zaurus/stand/zbsdmod/zbsdmod.c?r=1.12#94 --- Izumi Tsutsui
