Unfortunately, you can only extend the size of the log when the log is on
an external device. By default the log is in the middle of the filesystem,
and changing its size could well involve moving things out of the way, it
would certainly involve removing the newly used space from the available
free spare. All technically feasable, but not there in the code as it.
