Linux 5.4 + ext4 casefold adventures!
December 20th, 2019
----------------------------------------

Been a while since I wrote anything up here, I was hesitant to write much
while my wife was going through the immigration process, we have a few
cyberstalkers. :o

Anyway, I just rebooted this server in order to transition from kernel
4.19 to 5.4, I'm interested in the new case-insensitive file/directory
name option on ext4... It's a bit of a pain in the ass (read: impossible)
to get going on existing systems... First off the casefold option must be
enabled in the filesystem features, but it can't be set with tune2fs, it
can only be set with `mkfs.ext4 -O caseflag'; or in other words only at
filesystem creation... I'm far too lazy to do that today :)
Furthermore after you have a working ext4 filesystem with the caseflag
option, you need to set the F attribute (i.e. chattr +F) on any EMPTY
directories that you want to be case insensitive.

I'll get off of my butt eventually and get it working. Stay tuned. :)
