23 Sometime back the kernel devs decided to 'remove' the ext2 / ext3 fs
24 drivers.
25 The ext2 / ext3 fs drivers are NOT available.
26 Any choice of ext2 / ext3 forces the use of the ext4 fs driver.
27 If I could use the real ext2 / ext3 fs drivers ...
28 ... I would in the blink of an eye.

30 ext2 / ext3 are the definition of 'stable' file systems.
31 ext4 .... unstable, still in development, prone to breakage.
