Right, it was just pretty unfortunate in this case (and I heard of another one) that the person had his source tree mounted on a vinum volume, so he could no longer access it :-) If this happens to anybody else, there's a version of the vinum kld compiled this morning on ftp://ftp.lemis.com/pub/vinum/vinum.ko. > kget(8) also will need a recompile. > > People who are running -current for stability had better be damn careful > and be very selective about what they choose to run as a stable snapshot. I think the real problem is that the klds get built with "make world" and not with a kernel build. How about changing that? I've got the opposite problem on another machine: I did a make world, but not a reboot, and now my Linux emulation is broken.
