Deleting all kernel debugging symbols:

	find /boot -name "*.symbols" | xargs rm

and (optionally) building your new kernel without the config line

	makeoptions DEBUG=-g

should also do it:

> find /boot -name "*.symbols" | xargs rm
> du -h /boot/
4,0K    /boot/zfs
4,0K    /boot/firmware
  85M    /boot/kernel
  28K    /boot/defaults
4,0K    /boot/dtb
4,0K    /boot/modules
  85M    /boot/kernel.old
173M    /boot/
