A little more info on the second issue: The Distrobox command that built it is
```
distrobox create \
--image quay.io/toolbx-images/fedora-toolbox:40 \
--name Fedora40 \
--home $HOME/Fedora40Distrobox \
--init \
--additional-packages \
"systemd git git-lfs mlocate time tree vim zsh zsh-autosuggestions zsh-lovers
zsh-syntax-highlighting" \
--nvidia
```
These are the repositories:
```
$ ls -al /etc/yum.repos.d/
total 32
drwxr-xr-x. 1 root root 334 Feb 13 00:00 .
drwxr-xr-x. 1 root root 2972 Mar 26 23:49 ..

```
Should the "rawhide" repository be there? I haven't tried other images yet -
that's next.
