1 After multiple fs corruptions and nothing untoward shown by smartctl (I think)
2 I decided to move to ext4.

4 Now when I boot I see a message about my / fs which says Opts: (null)

6 ============================================
7 dmesg | grep -i EXT4
8 Command line: root=/dev/sda7 rootfstype=ext4

26 What is the meaning of Opts: (null) ?
27
28 All ext4 partitions were created with a number of options; e.g.
29
30 Filesystem features: has_journal ext_attr resize_inode dir_index filetype
31 needs_recovery extent flex_bg sparse_super large_file uninit_bg dir_nlink
32 extra_isize
33
34 but default mount options are shown as:
35
36 Default mount options: (none)
37
38 Should I be defining something in fstab? (currently I only have noatime).
