title: Updating Fedora with Read-Only Root Filesystem

When using `dnf system-update` on a Fedora machine that has a read-only root
filesystem, it is important to make sure that the filesystem will be mounted
read-write automatically first.  Edit `/etc/fstab` and change it to `rw`
before rebooting, lest the update will fail.

I imagine the offline update process really should remount the root filesystem
on its own, but that does not appear the case, at least for now.
