Just for the record and to avoid further confusion, building a kernel with debug symbols does not take any more space in root. Another copy of the kernel is built but not installed into /kernel. The copy of the kernel in /kernel is always symbol-less. Also, at the start of this thread, the OP said that he did a buildkernel and a buildworld. This is broken and may produce a non-bootable kernel. Always buildworld and then buildkernel so that the new toolchain is used to build the kernel. (This also has nothing to do with the original issue of the amount of space in the root partition being too small for amd64 systems, but I am hoping to avoid future issues.) -- R.
