Prevent `os.chdir` from resolving symbolic link

问题

On all the machines on my cluster, my home directory is mounted from the NFS server as /home/drive1/username. On the NFS server, the folder /home/drive1/username is a symbolic link to /drive1/username.

Running:

$ python -c "import os; os.chdir('/home/drive1/username'); print(os.getcwd())"

on any machine other than the NFS server prints:

/home/drive1/username

but on the NFS server, the same command prints:

/drive1/username

Is there any way to prevent Python os.chdir from walking the symbolic link? This makes it difficult to specify the correct path when submit jobs from the NFS server to the worker nodes.

Edit:

Note that

cd /home/drive1/username
pwd

works as expected on all machines.
