I have a feeling that when this is resolved I'll be doing a face palm and saying "of course, you idiot!" but I'm not seeing the answer right now.
I have a local repo that I maintain using rsync from an official Fedora mirror site. This repo is located on one of my "always-on" servers using a systemd automount in /etc/fstab:
worldsys:/install /install nfs rw,x-systemd.automount 0 0
This works great for installing new packages and doing updates, but it does not work for doing dnf system-upgrade. The packages are not copied when the "system-upgrade download" is done because they are already on a locally-available file system, but when the "system-upgrade reboot" is done, the upgrade fails (presumably because the remote file system is not available at the point of the upgrade boot where the upgrade transaction is run, either because the network is not up or the automount is not happening).
Is it impossible to do a system-upgrade from a remote-mounted repo (which would defeat much of the purpose of maintaining such a repo), or is there a way to make the network come up and the automount happen at system-upgrade reboot time?
I suppose I could set up a web server on the system with the repo so that the download would be forced at system-upgrade download time, but that's a big hammer for a small nail that I would prefer to avoid.
