I think the problem *may* be that systemd has a default 90 second timeout on jobs, including unmounting root. On an external USB drive, due to slower transfer times, the shutdown process of all the VM's, killing processes, flushing buffers, etc., happens to take long enough that a clean unmount of the drive doesn't get a chance to occur, leaned to a corrupted filesystem. If I shut down each Appvm manually before finally doing the reboot, the work left to do on shutdown lets the unmount occur with in 90 seconds, so the drive shuts down cleanly. I think that's what I've been seeing, anyway. There's a lot of disk activity while systemd talks about outstanding jobs, and while the time remaining of waiting for the jobs, ticks down to zero. Now, why the fsck on boot fails (and things fall into r/o mode, and fail thus hang the boot sequence), I'm not sure. It could be a similar problem, that startup jobs aren't happening within the 90 second default job window for systemd (due to slower USB transfers, and the time taken for the fsck), and the boot process gives up. People with internal drives and killer machines wouldn't see this issue. I'm going to try cranking up DefaultTimeoutStartSec and DefaultTimeoutStopSec in /etc/systemd/system.conf, and see if that improves the situation. I'll also scrutinize systemd-analyze (which I just learned about, being an old-school /etc/init.d guy, lol) and see if that confirms my suspicions.
