I’ve messed up my system so many times over the years that now I think I secretly get excited when it accidentally happens. Maybe I’m a masochist, but I actually enjoy trying to understand what went wrong. A USB stick with a light weight Linux distro and chroot you can usually get back in there and look around at the damage.
That’s what I was wondering. Seems like a recipe for disaster having your main system be several versions behind them shoehorning bleeding dependencies for AUR programs into the mix.
