Package: systemd Version: 227-1 Severity: important --- Please enter the report below this line. --- I've downgraded all systemd components to 226-4 in the meantime.
The machine in question has /var, /tmp on ZFS (/tmp is mounted "legacy style"). Because these are needed fairly early in the boot process, I mount the ZFS filesystems very early in the boot process, immediately after systemd-udev-settle. At the end of the boot, systemd decides to unmount lots of things, including the "legacy" mountpoint (/tmp) and zfs-style mountpoint /var. Even more strangely, it attempts to unmount / (and fails). If I log in, and mount the file systems again, and then log out: systemd again tries to unmount everything. Because it's attempting to unmount root (which has nothing to do with ZFS) and the "legacy mount" /tmp, it would seem that this is a bug rather than some misconfiguration. The log seemed to suggest that the unmounting happened when "root slice" was closed or something--I don't remember the exact error message.
