The repo seems to say that Krusader has now been updated to Plasma 6,
but even though the version in Fedora 41 says it's '2.8.1 "A New Day"',
when I attempt to start root mode Krusader from the Krusader menu it
fails, complaining
Cannot start root mode Krusader, /usr/libexec/kf5/kdesu not found or
not executable. Please verify that kde-cli-tools are installed.
Indeed kdesu is not in that kf5 directory, but there is a kf6 folder
that *does* contain it, it's just not being referenced :-(
