here's some testing under fedora

Initially it didn't work; however once I did dnf install bash-completion, it started working with zero config:

[root@55c4eab46a78 ~]# earthly --
--allow-privileged         --buildkit-host            --git-password             --max-remote-cache         --push                     --ssh-auth-sock            
--artifact                 --buildkit-image           --git-url-instead-of       --no-cache                 --remote-cache             --strict                   
--auth-token               --ci                       --git-username             --no-output                --save-inline-cache        --use-inline-cache         
--build-arg                --config                   --image                    --platform                 --secret                   --verbose                  
--buildkit-cache-size-mb   --conversion-parallelism   --interactive              --pull                     --secret-file         

Then here's a test of the uninstall

[root@55c4eab46a78 ~]# ls /usr/share/bash-completion/completions/earthly 
/usr/share/bash-completion/completions/earthly   <---- file exists
[root@55c4eab46a78 ~]# dnf remove earthly
