I posted a new template that does not have the resume problem.
https://github.com/sdwru/glibc-debian-10/releases
https://github.com/sdwru/glibc-centos-8/releases
I believe it was because of mariadb which should not have been installed
on the template in the first place. This problem was reported years ago
so I don't think it is anything new with this template or OS. If you
stop mariadb then you can suspend/resume.

Any other issues should be posted there in the issues area there.

I am not a fan of mail lists at all and frankly, I don't understand why
anyone still uses them.
