comment bash --debugger does not work on with bash 4.3 on a script with no arguments after installing bashdb
Thanks, but that was not the problem. I debugged the source code of bashdb, and found out that you always have to give an argument, in my case an empty string, because I had no arguments. So $ bash --debugger myscript.sh "".

supervisord is like systemd, but this is not what i meant. I would like to know how to extend an image.

comment bash --debugger does not work on with bash 4.3 on a script with no arguments after installing bashdb
Hi, it doesn't work. By the way, bash --debugger /usr/bin/bashdb my_script.bash works. It seems I can only debug /usr/bin/bashdb with bash --debugger. But that does not help me with $0, because it is still /usr/bin/bashdb instead of my_script.bash.

comment In fedora container systemctl gives Failed to get D-Bus connection
Indeed, systemd was not running. Now I understand the error! Why is it not good to use systemctl in containers? Because for example instead of systemctl enable sshd, I have to do ssh-keygen -A and then /usr/sbin/sshd.
