Unless you are using an initramfs, Linux doesn't know what filesystem you are using on your root partition. Linux tries to mount it using all built-in filesystems available, listed in /proc/filesystems, in that order. If you have ext2 and ext3 built-in, Linux tries those before using ext4, and it looks something like this: EXT3-fs (sda3): error: couldn't mount because of unsupported optional features (240) EXT2-fs (sda3): error: couldn't mount because of unsupported optional features (240) EXT4-fs (sda3): mounted filesystem with ordered data mode. Opts: (null) I believe this is harmless. If you really want, you can get rid of those errors by using the rootfstype=ext4 kernel parameter. -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
