It depends on what features you know about/need ;) Comparing with btrfs [1], with ext2/3 (and the upcoming ext4 [2], which is not more than another patch over ext2) you can't do: - object level data mirroring - Subvolumes and snapshots - fs level raid - online fsck - fsck 1 TB filesystem on less than a couple of days ;) - Never run out of inodes. ext4 still (we're on 2009!) suffers from this one :( - Online FS growth and shrinking - FS level compression - Online defrag (*) - Tail packing (*) - And much more (*) also supported by ext4, but not ext2/3 Although many of that features are useles for devices like Freerunner, some other would make a difference: dynamic inode allocation, tail packing, fast and online fsck... And reiserfs is the closest to btrfs we have on OM kernel :) What is true is that kernel developers are making clear that ext4 is not "the future fs", but "the interim fs until btrfs makes stable" > anyway, how would i go about changing to something more modern? say > ext4 or btrfs? > > is possible without a format/reinstall?
