This would require also the debug package, see below.

Not so simple. Debug symbols are packaged in a *-dbg
package. Unfortunately, this doesn't exist for every released Emacs
version.

On Ubuntu 19.04, which I am using, I cannot see any Emacs debug
package. On Ubuntu 18.04, the recent LTS version, there is emacs25-dbg
25.2+1-6 "Debugging symbols for emacs25".

With Debian, the situation is even worse. Debian 10 (buster) does not
offer any Emacs debug package yet. Debian 9 (stretch) offers emacs24-dbg
24.5+1-11+deb9u1 "Debugging symbols for emacs24".

Shall we add debug packages to our description, even with this limited
availability?

I'll wait until Monday, then I'll have a Fedora machine @work. Good for
adding the Red Hat case.

Best regards, Michael.
