Anyone here on the list having an fedora Server (newer versions) for serving diskless-clients (running fedora)?

I do not remember where was this option readonly=yes? Inside FAI?
Something fedora specific?
Using the nfsroot for diskless clients always will use overlayfs for
making the whole filesystem writable, even if it's only eported
read-only.

There may be problems, if you export it via NFS v4, but somewhere in
the mailing list archive there's a mail how to fix that.
Read:
https://lists.uni-koeln.de/pipermail/linux-fai/2019-September/012351.html

I have written an article in the FAI wiki (which is currently down)
about using the nfsroot as a live system for diskless clients.
Here's the link to archive.org:
https://web.archive.org/web/20230517095137/https://wiki.fai-project.org/index.php/Use_nfsroot_for_diskless_clients

In the next FAI version, building live systems will be much
easier, you can then also create live ISO images using "fai dirinstall"
and then fai-cd.
