bash-completion package is not functional

[dmcilvaney]

Describe the bug
The bash-completion package does not function when installed.

To Reproduce
Steps to reproduce the behavior:

run Mariner 2.0 docker container

ls -#<TAB><TAB><TAB>
 # Nothing occurs as expected

# Install package
tdnf -y install bash-completion
ls -#<TAB><TAB><TAB>
# Nothing occurs again...

# Try reloading bash
bash
ls -#<TAB><TAB><TAB>
# Still nothing

# Manually source script
source /etc/profile.d/bash_completion.sh 
ls -#<TAB><TAB><TAB>
# !!! It works!
# Should see:
# --all                                      --dereference                              --group-directories-first                  --indicator-style=                         --recursive                                --time

Expected behavior
Installing the bash-completion package should cause tab-completes to start working without additional configuration.

bash_completion.sh is loaded by /etc/profile which is run on user login:

for script in /etc/profile.d/*.sh ; do
        if [ -r $script ] ; then
                . $script
        fi
done

You might have to logout/login to have bash completion loaded.

Could we add a %post script to source these, add them to .bashrc and source that, or something like that?

Or, since the rpm transaction scripts are run as a different user, maybe that wouldn't work? Therefore, the %post script sourcing might not be reflected in the open shell?

@zcobol Thanks for the pointer, was working in a docker container and didn't even think to try logging in/out. Should have dug one layer deeper.

@Camelron My understanding is you generally can't force an outer shell to change its environment from a child process. I'm not aware of any way to trigger it. This is probably just a quirk of changing /etc/profile.d/*.

Hmm, interesting data point, VSCode terminal doesn't seem to work, but ssh and direct login DO work after a reboot.
