How to handle outdated mirrors

[favetelinguis]

Sorry in advance that this might be a very basic question, I am using your image to build a distrobox and it often works great for that. However sometimes I start to get the error below when i run the command:

podman build --no-cache -f ArchL1 -t devbox .

This is how my image looks.

So I guess every time you rebuild this image which is once a week the mirror list will get updated, if however the mirrors goes stale before that I need to copy the following into my image also. Is this the correct understanding on how to depend on this image?

# update mirrorlist
ADD https://raw.githubusercontent.com/greyltc/docker-archlinux/master/get-new-mirrors.sh /usr/bin/get-new-mirrors
RUN chmod +x /usr/bin/get-new-mirrors
RUN get-new-mirrors
