Hi all,

I noticed that the part of **/etc/bashrc** that controls the PATH is doubled sourced event though the file attempts to prevent the double sourcing by checking if the _BASHRCSOURCED_ environment variable is set. if not it sets it but does _not_ export it. The check is therefiore useless and there’s no protection against multiple sourcing it.

The impact is that the PATH grows inside each Bash sub-shell.

The fix is simple, but the location of the check must move, otherwise interactive sub-shells won’t use the same prompt.

My questions:

1. Where is the Git repository where the source of the **/etc/bashrc** is located? It’s probably upstream, right?
2. Where would I find information to report this problem and propose a fix?

For reference, here’s the diff between the original /etc/bashrc on Rocky Linux 8.10 and a version I modified:

I did a little more digging, from Rocky Linux 8.4:

- `rpm -qf /etc/bashrc` identifies the package that provides **/etc/bashrc** : **setup-2.12.2-11.el8.noarch**
- `rpm -qi setup` provides a stale URL (`https://pagure.io/setup/`) that has been replaced by `https://src.fedoraproject.org/rpms/setup`
