It is possible, but difficult, to resize a replica set oplog after it is
allocated. Due to the difficulty it is more likely to be error-prone, so we
have avoided doing that.

For 64-bit Linux systems, the minimum is 512M. We could make this
configurable, but you would be stuck with whatever you configure it to -
there will be no resizing.
