[Unionfs] pwd/getcwd bug

[Darrick Hartman (lists)]

I know I saw a post on this from April in 2006, but I never was able to 
find a work around or a fix.

In my case I'm serving a web page (which is an admin interface) for a 
small device using the latest unionfs (2.2.2) patch for Linux 2.6.20-21. 
  If the web page contains a php system() or exec() call, the following 
errors appear on the web page (even though the function completes 
correctly and displays the correct information.

shell-init: error retrieving current directory: getcwd: cannot access 
parent directories: Inappropriate ioctl for device

If I serve the web page out of the underlying read-only branch of the 
unionfs mount, it works without the errors.

I've seen similar errors when ssh'ing into the box as well.

Any ideas?  Is there a place to file a bug report?

Thanks,

Darrick
