I have to say that I run many graphical applications via podman and this saves
my a...
The problem are for example CAD-software vendors. Their (very powerful and
expensive) software *only* runs on e.g. RHEL7.
Then containers are your saviour!
Just use the centos7 container and "yum" the needed packages for a graphical
system and your in business (while keeping your desktop machine bleeded edge).
Much less overhead than a full virtual machine.

I love podman and the possibility to also run graphical applications in them.
(normally in a vnc-server, as vnc is also such a great tool to improve your
life).

Viele Grüße

Michael
