I believe you'll get at least one response that it makes it harder to
keep the straight which symbols match which kernel.  One may
'mv /boot/kernel /boot/kernel.good-fifo' and forget to
'mv /var/crash/kernel /var/crash/kernel.good-fifo'.  By keeping kernel +
symbols in one place this isn't an issue.

I think a better approach would be to split the kernel into runnable part
and symbols part.  The symbols would be bzip2'ed and kept beside the
runnable part.  kgdb would grow support to read a bzip2'ed file (using
libbz2.so).  Then the space issue wouldn't be such an issue.
