And again, you are glossing over the matter of the relative likelihood of data loss with various filesystems. It suits your purposes to turn it into a black and white issue. "Ext3 can lose your data too!", you cry.
Well, Both my mattress and J.P. Morgan *could* lose my money. So putting my money either place represents equal risk. If I understand you correctly, you are saying that Ext3 mounted data=ordered, Ext4 mounted with the defaults, and XFS mounted with the defaults, all represent equal risk to our data because any one of them *could* conceivably lose our data.
