I think I've definitely switched teams to the so called "immutable" distros. They just work (tm), except when they don't, but that's besides the point. They are so easy to set up, and I truly think that this idea of letting the distro set up your partitions is the best way to go about it. You want to "dual boot"? Buy another HDD/SSD/etc, chud, stop being poor. Everything else is also seamless for the most part, and despite its short comings I think Flatpak might truly be the best option for regular user-facing programs, and for any other case Distrobox with your meme le haxor distro of choice is good enough.
