Install or update a single package from Fedora Rawhide

I wanted to update Waybar to the latest release (v0.14.0), but the version in the Fedora 42 repository was v0.13.0. I found this question on Stack Overflow which showed me how.

First install the Rawhide respository:

sudo dnf install fedora-repos-rawhide -y

Then install or upgrade the package you want, selecting the Rawhide repo and version of Fedora you want to check (ie current version +1):

sudo dnf --disablerepo=* --enablerepo=rawhide --releasever=43 upgrade waybar
