How to persist changes in .bashrc across upgrades


I’ve done a few minor convenience changes to .bashrc that I’m used to have on every system:

alias ll='ls -l'
alias lla='ls -la'

How can I persist these so that they will still be there after an upgrade?
I’m on rolling so it would be a bit annoying to lose them every time.


Could someone please provide me some info here on how this could be achieved?
Or tell me that’s impossible - which I hope it is not…

You can track it here

Thanks! Are there any workarounds possible? Documentation?
