Sun gave the three letter acronym "ZFS" to our new filesystem. However, in reality it should really be called "CDF" (Coffin Dodger Filesystem). This is because it evades death. Due to it's self healing ability to maintain and correct integrity, it checksums everything and is therefore ideal to save things that you may want to use or look at when you are a pensioner. Like pictures of your first girlfriend, that you may have forgotten about when you have retired. Unless you are back with your first girlfriend or you never left her in the place. Need to stop now.

Logical speaking if we normalise ZFS into it's components it is coffin dodging (avoiding death) for data. The data can never die if you use ZFS, so it is a Coffin Dogging Filesystem.

NB, where I used to live the term coffin dodger means pensioner, dodger means someone who avoids things. If the English does not make sense I am afraid that you will have to look up coffin and dodger separately.
