1.5.24 unable to access files via root / (forward slash)

Hi,

I'm trying to access files for reading via the / directive, i.e. vi /usr/foo.txt
However, this will not open foo.txt, vi creates a new file in the current directory instead.
I can cd to the /usr directory and open the file with vi usr.txt. I'm using vi as an example, I'm actually trying to compile files with a gcc variant, and it can't access files the the / path either.

I've checked with the mount command that / is mounted, and it reports:
D:\cygwin_root on / type system (binmode)
Output from ls -lg /usr shows
-rwxrwxrwx 1 mkgroup-l-d 13 Feb 20 13:33 foo.txt
Which seems ok from what I've read?

I've attached the output from cygcheck using cygcheck -srvv. Apologies if I'm missing something really simple here.

cygcheck.out

Thanks in advance,


Jeff.
