Comment (by knarf):

 I thought about that. Unfortunately, the PWD solution has the problem that
 PWD isn't updated when chdir() is called within simfactory. This is
 usually fine for the Cactus source dir, since that is asked for at the
 very start of commands. Using PWD in general would require to write a
 wrapper for chdir() and to consistently use it.

 I didn't find a better way to implement this, despite some people having
 the same problem on the web. The system call pwd() will dereference
 symlinks no matter what - that is the standard. The other way to get to
 the symlink-path is using the environment, but python doesn't update that
 when it changes directories, so os.environ.get("PWD") might actually not
 point to the current directory.
