[Tfug] Filesystem/Distro suggestions?

[Chad Woolley]

Yeah, reliability is hard to test.  However, there's some interesting
comments on this article:

Basically, you could pull the plug during different file operations.
Do that multiple times in a controlled way, on multiple filesystems,
with different amounts of data in the filesystems, and different file
sizes.  Then measure the amount/type/severity of errors for those
scenarios.

Not perfect, or necessarily even indicative of reliability, but
definitely quantifiable.
