Systemd to the rescue
I had a weird failure after installing 16.04 on an external disk.
It wasn't the first time I did it and since the boot problems were solved it generally works very well, better than 15.10 bu that's in MNSHO no great feat.
This time a reboot caused significant problems by getting stuck at an initramfs prompt.
Right, I might have done something wrong so the easiest was to reinstall.
And ended up the at the same point.
Now systemd offered showing a log so I ran the provided command.
It was a looong log but real errors were either highlighted or even in red.
And towards the end one of them told me the file system on sdd6 (/home) was damaged and required fsck.
Being on an external drive this was easy and indeed, a few damaged inodes were fixed.
Now all is well again.
PS, I post this here because older versions don't show this capability.
