For me it’s PeppermintOS.
I started my Linux adventure a few years ago, and haven’t owned a Windows PC since.
I currently use Arch on my main rig, and I wanted to install Linux on two old laptops that I found laying around in my house
I then remembered the first distro I ever used, which is PeppermintOS, and I was amazed at the latest updates they released.
They even have a mini ISO now to do a net-install with no bloat, with a Debian or Devuan base.
Sadly, I believe the founder passed away a few years ago, which is why I was really happy to see the continuation of this amazing project.
Yes, that’s true. You lose reproducibility by using distrobox. But so far I did not need distrobox on my Guix laptop, the nonguix repo was enough. It was just a suggestion for somebody caring more about availability of packages than reproducibility to use Guix as the stable base and distrobox on top.
