Some features edit `.bashrc` and `.zshrc`, such as [stuartleeks/shell-history](https://github.com/stuartleeks/dev-container-features/blob/main/src/shell-history/README.md) which needs to `chown` a folder that is mounted.

Some features edit `.bashrc` and `.zshrc`, such as [stuartleeks/shell-history](https://github.com/stuartleeks/dev-container-features/blob/main/src/shell-history/README.md) which needs to `chown` a folder that is mounted.

The issue I'm experiencing comes when I use my custom dotfiles repo, which replaces any `.zshrc` files with a custom one, so any changes made from features are basically deleted.

Do you have any idea on how to fix this? I could source the old `.zshrc` in my custom file, but I'm not sure if that's a good idea. I was also thinking that there can be a "best practice" for devcontainer features to add stuff to `.zshrc.devcontainers` (and so on for bash and fish) so people can take this into account when making install scripts for devcontainer dotfiles.
