I edited a file on my Raspberry Pi.
I then rebooted it.
It then couldn’t mount the root filesystem, which is ext4.
WHY do people still do it ? The EXT file system is stupid, unreliable, and a dark deep pit of fsck-needing-to-run-whenever-the-thing-was-modified.
So, here I am fsck-ing a frigging SD card on my main Linux box which is happily running XFS.
If you hate file-system corruption just stop using EXT(x) please.
