Booting From a ZFS Root File System. Both SPARC based and x86 based systems boot with a boot archive, which is a file system image that contains the files required for booting. The root file system that is selected for booting contains the path names of both the boot archive and the kernel file.

Making going back and forth between snapshots easier as all the logfiles and stuff will be kept. If someone want to have another root (try something), one can simply switch the mountpoints and be good to g Live Upgrade - When a UFS root file system is migrated to a ZFS root file system, the default swap size for the ZFS BE is calculated as the size of the swap device of the UFS BE. The default swap size calculation adds the sizes of all the swap devices in the UFS BE and creates a ZFS volume of that size in the ZFS BE. If no swap devices are defined in the UFS BE, then the default swap size is.
