Hi All,

I write a script to clean up WORKDIR that remove the obsoleted packages' 
build directories.
The script accept a argument as BUILDDIR and I use this clause to 
identify the WORKDIR:

      workdir = os.path.join(builddir, 'tmp/work')

Then validate the workdir exists or not. It works for me but hardcode 
here as Richard point out.
So is there  a better way to get the WORKDIR here? Thanks.

Regards,
Kai
