as with Ubuntu snaps, first get rid of flatpaks
# dnf remove $( rpm -qa|grep flatpak)

purge Gnome?
   # dnf remove --setopt protected_packages= gnome-shell
   # dnf remove PackageKit gnome-software
   # rm -rf /var/cache/PackageKit/

who still eats my free disk space?
   rpm -qa --queryformat '%{SIZE} %{NAME} \n' | sort -n -r | head -40


keep monitoring

analyse and tune more? pcp

   dnf install pcp pcp-system-tools
   systemctl enable --now pmcd.service
   systemctl enable --now pmlogger.service
   systemctl status pmcd pmlogger
   less  /var/log/pcp/pmcd/*


virt-manager as user, fresh install?

   getent group | grep libvirt
   e.g.
   usermod -a -G libvirt user
   vi /etc/libvirt/libvirtd.conf
   .
   .
   unix_sock_group = "libvirt"
   .
   .
   unix_sock_rw_perms = "0770"

get fedora

version 43 and extra alternatives

btrfs!
