For the purposes of creating sparse files the truncate command is
preferable to fallocate because generic sparse files are more widely
supported by older platforms. Specifically Debian Wheezy which is
based on a 2.6.32 kernel used ext3 by default which at the time did
not support it.

The ziltest.sh script is a test case designed to verify the correct
functioning of the ZIL. It's being added to the scripts directory
so it can be easily added to the automated regression testing.
The general idea is to build up an intent log from a bunch of
diverse user commands without actually committing them to the file
system. Then copy the file system, replay the intent log and
compare the file system and the copy.
