question regarding kernel building framework

[Chris Pressey]

If I do a 'make' from inside (say) /usr/src/sys/vfs/fifofs, it creates
'@' and 'machine' symlinks in that directory. (ok)

If I do a 'make clean' from the same directory, it removes those same
symlinks. (good)

If I do a 'make clean' from /usr/src/sys/vfs, it still removes those
symlinks. (also good)

But if I do a 'make clean' from /usr/src/sys, those symlinks aren't
removed.

This a bug... right?  Probably caused by the reoganization into sys/vfs?

(It happened to bite me during buildworld, by making
usr.bin/kdump/mkioctls create a list of far, far too many include files
(as it was recursing down the @ links) which caused awk to choke.)

I'll look into it if everyone's busy... (I'm a bit busy too now though)
