Wrong. You can just cp --rec --sym /cdrom/src/linux /usr/src/linux to
create a read-write /usr/src/linux with a heap of symlinks in them which
point to the CD-ROM.

This used to work... but the mkdep step was a whole lot slower.
Whatever. I've since switched to keeping all my sources under a CVS tree,
anyway. :-/
