Interesting effect.
I do have fstab entry
none / cygdrive noacl,binary,nouser,posix=0 0 0
And this is what I see with and without changes.
(3.2.0)
$ ls -ld /proc/cygdrive/{a..z} 2> /dev/null
drwxr-x--- 1 anrdaemon None 0 ��� 22 23:12 /proc/cygdrive/c
drwxr-x--- 1 anrdaemon None 0 ��� 30 18:05 /proc/cygdrive/d
drwxr-x--- 1 anrdaemon None 0 ��� 22 23:11 /proc/cygdrive/e
drwxr-x--- 1 anrdaemon None 0 ��� 11 21:27 /proc/cygdrive/w
drwxr-x--- 1 anrdaemon None 0 ��� 14 2018 /proc/cygdrive/y
drwxr-x--- 1 anrdaemon None 0 ��� 12 03:59 /proc/cygdrive/z
(snapshot)
$ ls -ld /proc/cygdrive/{a..z} 2> /dev/null
drwxr-x--- 1 anrdaemon None 0 ��� 22 23:12 /proc/cygdrive/c
drwxr-x--- 1 anrdaemon None 0 ��� 30 18:05 /proc/cygdrive/d
drwxr-x--- 1 anrdaemon None 0 ��� 22 23:11 /proc/cygdrive/e
drwxr-x--- 1 anrdaemon None 0 ��� 11 21:27 /proc/cygdrive/w
lrwxrwxrwx 1 anrdaemon None 35 ��� 14 2018 /proc/cygdrive/y -> //HOSTING64.DARKDRAGON.LAN/wwwroot/
lrwxrwxrwx 1 anrdaemon None 35 ��� 12 03:59 /proc/cygdrive/z -> //DAEMON1.DARKDRAGON.LAN/anrdaemon/
I think I like these changes.
Thank you very much.
