We do respect the mount options in fstab for the root partition when root is mounted from the initrd: $ cat /etc/fstab | grep " / " /dev/mapper/main-root / ext3 relatime,errors=remount-ro 0 1 $ mount | grep " / " /dev/mapper/main-root on / type ext3 (rw,relatime,errors=remount-ro) $ cat /proc/cmdline root=/dev/mapper/main-root ro vga=791 quiet Cheers, FJP -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
