Upgrade/compatibility impact
How To Test
Only try the following if you are confortable debugging an un-bootable system and have made backups!
$ sudo rpm-ostree kargs --append-if-missing=rw
$ sudo ostree config --repo=/sysroot/ostree/repo set "sysroot.readonly" "true"
$ sudo systemctl reboot
Note that you can not "rollback" to the previous deployment to undo this change. You will have to boot into a Live ISO and edit the config file in the ostree repo to remove this config option.
User Experience
There should be no visible change in user experience.
Dependencies
Requires changes in Anaconda (config?) to set default kargs and property on ostree repo.
Contingency Plan
Revert the change before the release.
