Does NetBSD have any equivalent of SquashFS? This is used heavily in the embedded world on Linux, comes with good toolsets, supports compression and developers understand it. I'd prefer to re-use a known good solution rather than reinventing our own. Regarding appending the fs to the resulting binary, you'd need to do more than just that. Haven't checked, but afaik eg. the Xen loader will not load the extra parts without them being part of the ELF header.
