Package: zfs-fuse Version: 0.7.0-16 Severity: normal Dear Maintainer,
When installed on up-to-date stable Debian 9.1 system using systemd, the zfs-fuse package causes an ordering cycle at boot time: Oct 02 12:15:47 finmatkurk1 systemd[1]: sysinit.target: Found ordering cycle on sysinit.target/start Oct 02 12:15:47 finmatkurk1 systemd[1]: sysinit.target: Found dependency on zfs-fuse.service/start Oct 02 12:15:47 finmatkurk1 systemd[1]: sysinit.target: Found dependency on remote-fs.target/start Oct 02 12:15:47 finmatkurk1 systemd[1]: sysinit.target: Found dependency on remote-fs-pre.target/start Oct 02 12:15:47 finmatkurk1 systemd[1]: sysinit.target: Found dependency on nfs-server.service/start Oct 02 12:15:47 finmatkurk1 systemd[1]: sysinit.target: Found dependency on rpc-statd.service/start Oct 02 12:15:47 finmatkurk1 systemd[1]: sysinit.target: Found dependency on nss-lookup.target/start This seems to be because zfs-fuse.service is defined to start after remote-fs.target, but before sysinit.target: fimatkurk@finmatkurk1:~$ systemctl cat zfs-fuse # /lib/systemd/system/zfs-fuse.service [Unit] Documentation=man:zfs-fuse(8) Description=Daemon for ZFS support via FUSE DefaultDependencies=no Before=sysinit.target Before=shutdown.target After=remote-fs.target Conflicts=shutdown.target As a result, systemd attempts to break the loop. Usually it finds the right target: Oct 02 12:15:47 finmatkurk1 systemd[1]: zfs-fuse.service: Job zfs-fuse.service/start deleted to break ordering cycle starting with sysinit.target/start However, occasionally it seems to get it wrong: Oct 01 23:12:21 finmatkurk1 systemd[1]: dbus.socket: Found ordering cycle on dbus.socket/start Oct 01 23:12:21 finmatkurk1 systemd[1]: dbus.socket: Found dependency on sysinit.target/start Oct 01 23:12:21 finmatkurk1 systemd[1]: dbus.socket: Found dependency on zfs-fuse.service/start Oct 01 23:12:21 finmatkurk1 systemd[1]: dbus.socket: Found dependency on remote-fs.target/start Oct 01 23:12:21 finmatkurk1 systemd[1]: dbus.socket: Found dependency on remote-fs-pre.target/start Oct 01 23:12:21 finmatkurk1 systemd[1]: dbus.socket: Found dependency on nfs-server.service/start Oct 01 23:12:21 finmatkurk1 systemd[1]: dbus.socket: Found dependency on nfs-mountd.service/start Oct 01 23:12:21 finmatkurk1 systemd[1]: dbus.socket: Found dependency on network.target/start Oct 01 23:12:21 finmatkurk1 systemd[1]: dbus.socket: Found dependency on NetworkManager.service/verify-active Oct 01 23:12:21 finmatkurk1 systemd[1]: dbus.socket: Found dependency on dbus.socket/start Oct 01 23:12:21 finmatkurk1 systemd[1]: dbus.socket: Breaking ordering cycle by deleting job sysinit.target/start Oct 01 23:12:21 finmatkurk1 systemd[1]: sysinit.target: Job sysinit.target/start deleted to break ordering cycle starting with dbus.socket/start And when sysinit.target is not started, the system gets stuck at boot with no ways to log in. -- System Information: Debian Release: 9.1 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.9.52 (SMP w/8 CPU cores) Locale: LANG=C, LC_CTYPE=fi_FI.UTF-8 (charmap=UTF-8), LANGUAGE=C (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages zfs-fuse depends on: ii fuse 2.9.7-1 ii init-system-helpers 1.48 ii libaio1 0.3.110-3 ii libc6 2.24-11+deb9u1 ii libfuse2 2.9.7-1 ii libssl1.1 1.1.0f-3 ii lsb-base 9.20161125 ii zlib1g 1:1.2.8.dfsg-5 zfs-fuse recommends no packages.
