As an interested bystander (and large filesystem user), I'd say I tend to agree with Linus and Jeff on this one. * ext3 is arguably the main Linux filesystem: too important to keep "experimenting" with. * I'd encourage a >2TB version, but call it ext4. It makes it clear that you are entering new territory. * Take advantage of the switch to remove some of the backward compatibility cruft from the ext4 version -- make it a clean, explicit break. * [Possibly even inoculate ext3 against creeping featuris and work on cleanup and optimization instead.] This is not intended to slight the work/position of the ext3 developers, merely to inform them of an end-user's perspective. ---- Jeff Anderson-Lee Petabyte Storage Infrastructure Project University of California Berkeley "Simplify, simplify, simplify." -- Henry David Thoreau "I think one 'simplify' would have sufficed." -- Ralph Waldo Emerson
