Handle sysroot.readyonly=true migration in other rpm-ostree Fedora(s)

[Antonio Murdaca]

Hi folks, in rpm-ostree based systems like fedora iot I would love to handle the migration
process similar to what happens today in silverblue et all wrt sysroot.readonly
https://pagure.io/workstation-ostree-config/blob/main/f/postprocess.sh - unfortunately
that systemd service and script aren't packaged anywhere and I'd love to have it
versioned in RPMs to be used by other spins too. I couldn't find any other
conversations around this so I'm opening this one to discuss how and where such a
migration should be handled/shipped/run in other systems.
Thanks a lot in advance

Yeah, the motivating change clearly should have included Fedora IoT too.

Hmm.  Yeah, this is fair.  In retrospect honestly we should have probably done this in the
ostree core code to start anyways, and not done it "externally" in shell
script.
