From your initial bug report, it was not clear where exactly you got this message. Yes, systemd-shutdown does try to stop dm devices on shutdown. Christian's input was helpful. TBH, I find it rather broken having to embed a local copy of dm-ioctl.h to work around this. Christian, this version mismatch, does that happen for minor version differences as well, like say 4.10.0 vs 4.10.1 or only major versions like 4.10.x vs 4.11.x? -- Why is it that all of the instruments seeking intelligent life in the universe are pointed away from Earth?
