shared libraries

[justincormack]

If we renamed public symbols in the netbsd libs eg to __rumprun__name then we could load (host) shared libraries of NetBSD symbols, which we could construct from (pic) .a files.

We would have to rename all U symbols in the user code that are not rump syscalls or emul calls to this prefix.

Should work in theory, although you need to exclude some toolchain-related symbols. See src/sys/rump/Makefile.rump::__archivebuild for a starting point.
