Do you want to install Fedora CoreOS packages without having to reboot your entire system in order for the packages to be available? Just run
sudo rpm-ostree ex apply-live
after running your rpm-ostree install commands.
For example:
sudo rpm-ostree install nano sudo rpm-ostree ex apply-live
Note that this is not completely safe for multiple reasons, not even for seemingly innocuous utility packages like nano:
- As indicated by the
exin the command, theapply-livecommand is experimental - It might apply other changes from the new OSTree like automatically installed updated and hence might have effects
- When changing files on a system with productive services running, the services might crash or experience other issues. This might not happen immediately and it might be hard to debug especially in a complex environment. In case you want to safely update your services, it’s almost always best to just reboot into the new OSTree.
