Fabian Mastenbroek d8dafbe5c4
Build ZFS directly from upstream
This change updates the build process to directly build the kernel from
upstream sources, as opposed to requiring the Proxmox zfsonlinux
repository to build the patched sources.

Subject: [PATCH] Add systemd-unit for importing specific pools
The unit can be instantiated with a specific poolname, which will get imported
by scanning /dev/disk/by-id, irrespective of the existence and content of
/etc/zfs/zpool.cache.
the instance name is used unescaped (see systemd.unit(5)), since zpool names
can contain characters which will be escaped by systemd.
