Add systemd unit files for ZFS startup This adds systemd unit files replacing the functionality offered by the SysV init script found in etc/init.d. It has been developed and tested on Fedora 19, Fedora 20 and openSuSE 13.1. Four unit files and one target are offered. zfs-import-cache.service: Import pools from /etc/zfs/zpool.cache. This unit will wait for udev to settle. zfs-import-scan.service: Import pools by scanning /dev/disk/by-id for zvols. This unit will only run if /etc/zfs/zpool.cache is not present. This unit will wait for udev to settle zfs-mount.service: Mount ZFS native filesystems. It contains a dependency to be loaded before local-fs.target. zfs-share.service: Share NFS/SMB filesystems. This unit contains a dependency that will cause it to be restarted whenever the smb or nfs-server unit is restarted, restoring the shares added. zfs.target: This target pulls in the other units in order to start ZFS. It's the only unit that can be enabled/disabled, all other services are static and pulled in by dependencies. It will honour zfs=off and zfs=no options on the kernel command line.

Order zfs-import-*.service after multipathd If someone is using both multipathd and ZFS, they are probably using them together. Ordering the zpool imports after multipathd is ready fixes import issues for multipath configurations.

Systemd configuration fixes * Disable zfs-import-scan.service by default. This ensures that pools will not be automatically imported unless they appear in the cache file. When this service is explicitly enabled pools will be imported with the "cachefile=none" property set. This prevents the creation of, or update to, an existing cache file. $ systemctl list-unit-files | grep zfs zfs-import-cache.service enabled zfs-import-scan.service disabled zfs-mount.service enabled zfs-share.service enabled zfs-zed.service enabled zfs.target enabled * Change services to dynamic from static by adding an [Install] section and adding 'WantedBy' tags in favor of 'Requires' tags. This allows for easier customization of the boot behavior. * Start the zfs-import-cache.service after the root pivot so the cache file is available in the standard location. * Start the zfs-mount.service after the systemd-remount-fs.service to ensure the root fs is writeable and the ZFS filesystems can create their mount points. * Change the default behavior to only load the ZFS kernel modules in zfs-import-*.service or when blkid(8) detects a pool. Users who wish to unconditionally load the kernel modules must uncomment the list of modules in /lib/modules-load.d/zfs.conf.

systemd zfs-import.target and documentation zfs-import-{cache,scan}.service must complete before any mounting of filesystems can occur. To simplify this dependency, create a target that is reached After (in the systemd sense) the pool is imported. Additionally, recommend that legacy zfs mounts use the option x-systemd.requires=zfs-import.target to codify this requirement.

Use ExecStartPre to load zfs modules Commit 87abfcb broke the systemd import service by treating the ExecStart line as if it were a shell command that could be executed. This isn't the way systemd works and the correct way to handle this case is with ExecStartPre.
