Systemd GNOMEs have put that myth out to justify the crude new naming scheme for e.g. ethX - which, too, never change but behave deterministic. I would not blame changing names on the OS when the user moves hardware e.g. from sata0 to sata2 and keeps sata1 in place. Externals can change their device nodes randomly (I have a flaky Pi + enclosure combination where the drive can show up as sda or sdb depending on what it ate for breakfast). I suppose there are some people for whom that matters, and I do use a label in the autofs configuration on that flaky Pi (the only place I've ever used one). I've never seen an internal drive change its device node without a hardware change, but I suppose it would in theory be possible for it to happen if the system for some reason initialized an external drive attachment point first, or a drive ahead of it in the initialization order failed so hard that the system could no longer detect it. Regardless, I would class it as highly unusual on a system that doesn't have hot-swap drive bays or the like. Gentoo documentation doesn't indicate a preference for one type of drive identifier over the others. We could perform a survey, I suppose. E.
