---- oh no! --------------------------------------------------------------------
I back up shell profile/rc scripts before I add Nix to them.
I need to back up /etc/zshrc to /etc/zshrc.backup-before-nix,
but the latter already exists.

Here's how to clean up the old backup file:

1. Back up (copy) /etc/zshrc and /etc/zshrc.backup-before-nix
   to another location, just in case.

2. Ensure /etc/zshrc.backup-before-nix does not have anything
   Nix-related in it. If it does, something is probably quite
   wrong. Please open an issue or get in touch immediately.

3. Once you confirm /etc/zshrc is backed up and
   /etc/zshrc.backup-before-nix doesn't mention Nix, run:
   mv /etc/zshrc.backup-before-nix /etc/zshrc

We'd love to help if you need it.

The installer does not perform these actions automatically out of precaution.

Did you encounter a problem following the steps suggested by the installer?
