desktop/lightdm/ubuntu/view/head:/src/session-child.c#L509
Lightdm calls rename() on the xsession-errors file. In our deployment
many of our users have this file as a symlink. Their homedirectory is on
NFS and it will quickly fill their quota with bogus messages.
You should lstat() the file first. If it is a symlink, you can make a
new file at the destination and update the link. I can supply a patch if
you wish.
