I can see the motivation for having root be read-only if you *aren't*
using btrfs, but if we have a btrfs subvolume for the rootfs which is
snapshotted every time we perform a package/admin operation (and
perhaps also just on regular intervals for good measure), what would
we then gain by adding a read-only rootfs to the mix?

Thanks,

- Chris.
