By default zfs pools will now be trimmed on a weekly basis.
Trimming is only done on supported devices (i.e. NVME or SSDs)
and should improve throughput and lifetime of these devices.
It is controlled by the <varname>services.zfs.trim.enable</varname> varname.
The zfs scrub service (<varname>services.zfs.autoScrub.enable</varname>)
and the zfs autosnapshot service (<varname>services.zfs.autoSnapshot.enable</varname>)
are now only enabled if zfs is set in <varname>config.boot.initrd.supportedFilesystems</varname> or
<varname>config.boot.supportedFilesystems</varname>. These lists will automatically contain
zfs as soon as any zfs mountpoint is configured in <varname>fileSystems</varname>.
