Unfortunately there's no single up-to-date page that I can found that
best answer the question for beginners. The best doc in ubuntu is
probably https://wiki.ubuntu.com/Kernel/Reference/ZFS , which links to
https://pthree.org/2012/12/13/zfs-administration-part-viii-zpool-best-practices-and-caveats/
(warning: some entries might be outdated).

LXD's use of file-backed pool is perfectly described on the last
"caveats" entry: "Don't commit production data to file VDEVs. Only use
file VDEVs for testing scripts or learning the ins and outs of ZFS."

I tend to agree with Sean on this one though: the detailed discussion
for this is more appropriate on zfsonlinux mailing list, not here. I
just wish that ubuntu's docs would properly warn the use of
file-backed pool.
