I agree with this expression, but I don’t think this is the right situation to use it. PureOS is based on Debian which is one of the most stable OS out there. So what makes these crashes is not the OS per se but how Purism modifies it (and how much they test it), making it kind of a rolling release distro (which by nature breaks often). So Purism took a stable OS and transformed it into a “rolling relese” distro - and this is what’s causing these bugs and crashes. If I’m wrong, please correct me, I’m willing to learn and to understand this situation better myself.
As pointed here we could have different channels for users to choose from: stable, unstable etc…
I have PureOS on my laptop and Hyperbola (FSF-endorsed as well) on my desktop PC. So even tho Hyperbola is based on Arch - I found it to be more stable just because I’m using their “stable” branch, not the “testing” one.
