Hi, While installing OpenBSD 6.1, out of sheer, raging paranoia, I created the root file system with -O 0. This worked fine, until I had extracted everything, and the kernel crashed with some uvm error (the automagic reboot came too soon for me to jot it down -- is it such a good idea for bsd.rd to reboot so soon after a panic?), teaching me a lesson.
The obligatory fsck afterwards failed, as the level 0 fses are apparently considered to be too old. Fair enough, but is it such a good idea to continue support for them in newfs, and the kernel? I propose that we don't leave it half-supported like this, and that the relevant code be removed. Or is there some use for it, that I'm overlooking? --schaafuit.
