ZFS and unbreakable upgrades were introduced in an
earlier article. XercesTech has written a
detailed article on how apt-get and zfs join forces to provide a worry-free upgrade experience.
"While some operating systems provide the ability to roll back changes, they usually require significant time, or an experienced user with some external repair tools. The goal here is to be instant, if something goes wrong with an upgrade, it should be possible to boot into the old system without running any terminal commands, booting any rescue system or installation disc, or otherwise manually rolling things back."

I've been using Nexenta on my home server for about 6 months now. Initially I only installed it for ZFS, but I've since come to love it. In fact, the more I use it, the more I wonder how I coped before without Solaris Zones, ZFS and the lark.
