Tangentially: Qubes is very cool and I'm glad you find Fedora useful
as a base system. I work on Fedora CoreOS and have patches in a
lot of OS components; lorax, systemd, etc. If there's something blocking
you feel free to reach out and I may be able to
spend some time to help. Also, if you decide to investigate using
rpm-ostree for the Qubes dom0 - I'd be very interested in helping.
*guess* it's there for historical reason, from before
aufs/overlayfs being available. Is there any other reason for that?
There is one thing to consider; overlayfs-on-overlayfs is not supported,
so this would break podman/docker out of the box. But we could probably
have them fall back to the vfs backend; it's not like we really care a lot
about performance in the live media case.
One side note for OSTree-based systems we have some built-in support for
the read-only media case:
Which then changed to use systemd:
That still has /etc and /sysroot be read-only though. Extending to overlayfs
for / would allow e.g. `rpm-ostree install` to work as well if the upperdir
is on a writable layer.
