* You should set the <code>mountpoint</code> property of your ZFS filesystems to be <code>legacy</code> and let NixOS mount them like any other filesystem (such as ''ext4'' or ''btrfs''), otherwise some filesystems may fail to mount due to ordering issues. | * You should set the <code>mountpoint</code> property of your ZFS filesystems to be <code>legacy</code> and let NixOS mount them like any other filesystem (such as ''ext4'' or ''btrfs''), otherwise some filesystems may fail to mount due to ordering issues. | ||
* By default, all ZFS pools available to the system will be forcibly imported during boot, regardless if you had imported them before or not. You should be careful not to have any other system accessing them at the same time, otherwise it will corrupt your pools. Normally (for the common desktop user) this should not be a problem, as a hard disk is usually only directly connected to one machine. This behaviour can be disabled by setting <code>boot.zfs.forceImportAll = false</code>. | * By default, all ZFS pools available to the system will be forcibly imported during boot, regardless if you had imported them before or not.
