Case-insensitive partition under Linux

Question

Is there a way to format and use a partition under Linux which is case-insensitive?

I know of vfat, but was hoping I could find some alternatives. Any suggestions?

Gabriel Krisman Bertazi (who is the author of the case-insentive feature in ext4) wrote the blog Using the Linux kernel's Case-insensitive feature in Ext4. In short you need to enable the casefold property
```
mkfs -t ext4 -O casefold /dev/vda
```
For existing filesystems:
```
tune2fs -O casefold /dev/sda1
```
This doesn't automatically make the whole filesystem case-insensitive – each directory has to be marked so individually:
```
chattr +F ~/.wine
```
F2FS also supports case-insensitive name lookups via the casefold option
```
mkfs.f2fs -O casefold /dev/hda
```
XFS supports case-insensitive ASCII file names through the version=ci option
```
mkfs.xfs -f -n version=ci /dev/sda
```

You can create case insensitive filesystems with ZFS:

# zfs create -o casesensitivity=insensitive filesystem
