As far as the symbol table eating up memory goes, I just had a flash.
How about kernfs opens /netbsd and checks it against the in-core kernel
it sees, and if they match, it throws away all the stuff it doesn't
need and generates a symlink to /netbsd; otherwise, it keeps it around
(perhaps paging it, if someone wants to implement that) for perusal?

Then if you keep your kernel in the standard place, you pay essentially
no price (just a little code in kernfs); if not, you pay a price, but
everything still works.
