Correction, not only NTFS. Here's the source code comment:
Sorry, yes I forgot that it was coded to let Windows make the decision.
Unfortunately, in providing EXFAT, Microsoft has not seen fit to carry
over the same handling in the kernel as it does in NTFS.
ExFAT is based on FAT/FAT32, so it's understandable. I don't have ExFAT
available. Assuming your ExFAT drive is drive X:, can you please show
me the output of
/usr/lib/csih/getVolInfo.exe /cygdrive/x
If it returns different values than FAT, it might be worth to handle
specificially in Cygwin's mount code.
This is the output for L: drive, which is not a physical but logical
volume formatted EXFAT. Hopefully it doesn't alter the
characteristics/attributes. With a bit of extra effort, I could try with
a physical device (format a spare USB stick EXFAT through Windows):
$ /usr/lib/csih/getVolInfo.exe /cygdrive/l

Well, from my POV, yes. It doesn't make sense to use ExFAT for serious
work anyway, it's for SD cards and stuff like that.
I understand that. It's just that after years of being frustrated with
moving files around various NTFS partitions and fighting with
ownership/permission issues, especially where Cygwin work
files/directories are involved, I've decided that I should PoC a brave
new world.
That being giving up on security through file/folder ACLs, and just
mount FAT32 (or the candidate EXFAT) fs via as an encrypted logical
volume.
My Cygwin work will be access that way. If I need to move it, I move
the encrypted file only.
But I have to admit that the "con" of losing case-preservation is a
weighty one. [...]
