I understand the general theory behind this (a BE should include only system files and not user files), so for example zroot/usr gets into a BE but zroot/usr/home does not. My question is where can I read a document (or study a script) which creates all those datasets with necessary options for setting up a BE-friendly root zpool? Something like /usr/libexec/bsdinstall/zfsboot around "Default ZFS datasets for root zpool" but with a better description and learning value. Thanks in advance! -- Victor Sudakov, VAS4-RIPE, VAS47-RIPN AS43859
