The installation of VMware Tools fails when it tries to generate a new initramfs (also including its drivers). The problem is caused by missing spaces in the add_drivers lines in both our image's /etc/dracut.conf.d/vmware-fusion-drivers.conf file and vmware-tools.conf that VMware Tools generates. While we can only fix our own configuration file, it would probably be enough to avoid dracut errors during the VMware Tools installation.
Please see PR #67 for technical details.
