Yeah I want to change that 30 seconds to something much longer, like
one day.  In a perfect world, bcache could see when the drive is spun
up and write it opportunistically, or one day, whichever occurs first.

I have the rootfs on the SSD (a different partition than bcache), so
on the hard disk there is only one partition and the one mount is the
bcache backing one.

Thanks,
Ryan
