I've been experimenting with with ZFS (once known as the Zettabyte File System) as a filesystem to host LFS/BLFS using the SVN version of both. I've built support for ZFS using these tarballs: spl-0.6.1.tar.gz and zfs-0.6.1.tar.gz, supplied from http://zfsonlinux.org/.

Since I roll my own initramfs, I can mount the ZFS datasets just fine and boot into the ZFS-based system without any problems at all. I realize this is an advanced topic and a search for ZFS confined to this forum yields this result:

Sorry - no matches. Please try some different terms.

Is there anyone else out there trying LFS and ZFS? If so, what have been your experiences?

Why use ZFS as opposed to the more common ext* systems? What are the advantages?

To a large extent, much like the Linux from Scratch approach itself, ZFS represents another learning experience. In my case, there's no compelling reason for ZFS since LVM (with ext4 atop it as the filesystem) fulfills the need to expand the storage when needed. Nevertheless, the Wikipedia article does reveal the benefits of ZFS, particularly in large datacenters where so-called "silent corruption" can't be tolerated.

In any event, in my nearly-decade of using LFS as my primary daily computing environment, migrating one of my LFS platforms to ZFS has been a rewarding, sometimes frustrating but overall fun journey.
