Please follow these instructions to clean up the old backup file:
1. Copy $profile_target and $profile_target$PROFILE_BACKUP_SUFFIX to another place, just
in case.
2. Take care to make sure that $profile_target$PROFILE_BACKUP_SUFFIX doesn't look like
it has anything nix-related in it. If it does, something is probably
quite wrong. Please open an issue or get in touch immediately.
3. Take care to make sure that $profile_target doesn't look like it has

run:
$ /usr/bin/sudo /bin/mv $profile_target$PROFILE_BACKUP_SUFFIX $profile_target

In particular, the following files and directories MUST NOT EXIST!
- $ROOT_HOME/.nix-profile

If some relics are found and you want to keep them, it might be okay.
