I came home today and started my TV after I had a power outage, I only saw sad face over and over again.
I realized after ssh that / was mounted Read Only. I ran fsck on /dev/sda1 (I’m running from USB stick, sdcard only contains boot)
After check, some repaid and reboot - Everything fine!
So - a bug maybe? I couldn’t see info about scanning filesystem on boot. And I think sad face should have some messages too. This time ‘Filesystem corrupted, login with ssh and run fsck’ or something.
