Hi
Then _that's_ what needs to be said -- that Red Hat isn't able to allocate resources towards a 2nd filesystem. I'd more than accept that.
As far as I know no formal statements that ext3 supports all features that other filesystems do have been made by Red Hat. What has been repeatedly pointed out is the question of resources vs gain and requests in specific features that customers want based on their scenarios. If you do send in such a list to Red Hat support or partners , due consideration will given to those. For Fedora, get a detailed realistic plan to the fedora development list. Rest of the discussion doesnt really matter
