I believe Ted wrote a good summary of what combinations of options would need to be tested on a regular basis to get at least some confidence that the switch could work. > I admit I like having ext2 around for comparisons in bug situations. > It really helps to isolate the problem area. How painful is the > upkeep? Well, for me it's a couple of hours per week on average I'd say. Plus there is some work other people do when changing some VFS/MM interfaces influencing all the filesystems. The time I spend is enough to keep ext3 in a good shape I believe but I have a feeling that ext2 is slowly bitrotting. Sometime when I look at ext2 code I see stuff we simply do differently these days and that's just a step away from the code getting broken... It would not be too much work to clean things up and maintain but it's a work with no clear gain (if you do the thankless job of maintaining old code, you should at least have users who appreciate that ;) so naturally no one does it.
