Revision 0 is very old and misses a number of features. From man mkfs.ext2: Set the file system revision for the new file system. Note that 1.2 kernels only support revision 0 file systems. The default is to create revision 1 file systems. We are unlikely to have a lot of Linux 1.2.x users, so drop support for it. As revision 1 is the default, drop the -E revision argument to mkfs.ext2 for simplicity. Signed-off-by: Peter Korsgaard <peter@korsgaard.com> Signed-off-by: Julien Olivain <ju.o@free.fr>
