How to persist changes in .bashrc across upgrades

Hi,

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

force_color_prompt=yes
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.

Thanks.

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…

Thanks! Are there any workarounds possible? Documentation?
