I have more than 40 Tumbleweed installations. This was ~3 weeks ago, so I don't remember which PC this happened on. What I do remember is that fstab needed an update on account of a partitioning alteration, and I made a typo that made the root filesystem unavailable. That is what lead to the emergency console. At least one error scrolled offscreen before I could digest it, in part because the scrollback buffer disappeared after kernel 5.7, and in part because of all the useless error lines about Plymouth, which I have installed on zero of my 40+ TW installations, in addition to zero on more than double that number of Leap installations, most by selecting to taboo Plymouth at installation time.
