ext4

As ext4 was introduced as more reliable than ext3 with block journals, is there any chance to suppose it 100% reliable? What if enabling block journaling on it, which is disabled by default?

As friend's guide to explain my case in more detail: I have an embedded linux device, after installation keyboard and monitor is detached and it works standalone.

My duty is to make sure it has reliable file-system so with errors there is no way for manual correct faults on device. I can't force my customer to use a ups with each device to ensure no fault by power-failure.

What more can ext4 offer me besides block journaling?

Thanks in advance.
