Subject: Re: Unwanted case-insensivity in file name globbing
To: cygwin AT cygwin DOT com

Seems overly complicated for me. My current fstab looks like this:

# /etc/fstab
#
#    This file is read once by the first process in a Cygwin process tree.
#    To pick up changes, restart all Cygwin processes.  For a description
#    see https://cygwin.com/cygwin-ug-net/using.html#mount-table

# Device-       Mount-          FS-type         Options                 Ignored
# name          point
# ------------- --------------- ---------------
----------------------- --------------------

C:/Users        /home           ntfs            binary,posix=1,user     0 0
none            /               cygdrive        binary,posix=0,user     0 0

If I remember correctly the cygdrive thing is what automatically maps
all my C:. D:, E:, etc drives to /C, /D, E and so on.

The magic with posix is described here:
https://cygwin.com/cygwin-ug-net/using.html#mount-table

  posix=0   - Switch off case sensitivity for paths under this mount point
     (default for the cygdrive prefix).

  posix=1   - Switch on case sensitivity for paths under this mount point
     (default for all other mount points).

Regards,
