A list of reasons why Red Hat chose ext3 for our first officially supported journaling file system follows. Note that these reasons are not necessarily each unique to ext3 (some other journaling file systems share several of the points here), but the whole set of reasons taken together is unique to ext3.
Again, we do not claim that each one of these points is unique to ext3. Most of them are shared by at least one other file system. We merely claim that the set of all of them together is true only for ext3. The expressed needs of our customers drove our decisions about what feature set was important for us to support right now. In our judgement, ext3 currently has the best fit for our customers' requirements. We will continue to evaluate other file systems for inclusion in future versions of Red Hat Linux.
