I, too, ran into this problem, and it was also due to Novell, although
I believed at the time that our IT department had done it. In my
book, this is a bug on Novell's part, because the 'c:.' notation in
Windows-land means 'current directory on the C: drive.' This is
process-specific, for one thing; for another, as soon as a subprocess
happens to go to that drive and change the current directory, the path
is changed! This may not matter for the initial process upon login,
which won't do be changing its CWD on any drives, but it can mess up
other processes started later.
I ended up writing a BASH script which invoked a GAWK script (probably
could have combined the two) to fix the PATH variable. The latter
script invoked a quickie BAT script to get the CWD on the Netware
drive:
REM This command is a NO-OP so that ERRORLEVEL is reset to ZERO.
c:/WINNT/system32/attrib.exe . > nul
if . == .%1 goto end
cd %1 > nul
if NOT errorlevel 1 %1
if NOT errorlevel 1 %cygwindir%/bin/pwd
if . == .%2 goto end
%SystemDrive%
:end
The element of the PATH was passed as %1; I believe I used %2 during
testing so that I didn't change _my_ PATH. There was more involved
than this (I can post the scripts if anybody is interested), but the
idea is what's important: Use 'pwd' in a subprocess to print the
actual directory on the Netware drive and resplace the bogus PATH
element with the _real_ directory.
