Short story: I'm working on creating kernel module packages for the ZFS file system from zfsonlinux.org to be hosted at RPM Fusion and will utilize the akmods utility to make sure that new modules are built on kernel update. Problem: The zfs package also needs the SPL (Solaris Porting Layer) kernel module so I have to control the order the kernel modules are built and installed as the SPL one also has a kernel version specific devel package that ZFS needs to build. Question: What is the right way to make sure it's built prior to mounting non system volumes? Obviously you can't have your system volume be ZFS with this setup, but with the current performance and stability, you wouldn't want to. Here's my current service file for SPL: [Unit] Description=Builds and installs new kmods for SPL Before=local-fs-pre.target [Service] Type=oneshot ExecStart=-/usr/sbin/akmods --from-init --akmod spl-kmod [Install] WantedBy=single-user.target The one for ZFS is essentially the same except it also includes "After=spl-kmod.service, Requires=spl-kmod.service" in it.
