I think the idea is basically sound, but might want a few minor changes. What about: - kern_ksyms.c has a weak reference to the real db_symtab - initial link uses normal OBJS list and computes SYMTAB_SPACE - an additional object file containing just db_symtab is built from that - final link uses all normal OBJS and this additional one.
