I think its a great idea. Installs default to 256MB / (I think) and
this should be more than enough for a kernel.debug file and the rest
of the system utils that are installed. Installing the kernel.debug
used to be the default practice on fbsd but was change due to clumsy
admins filling up their / , most of the time do to files in /root .
