Why does booting of rhcos-4.2.0-x86_64-installer.iso land into dracut shell?

Issue

• Creating boot and master nodes on VMWare 6.7 using the rhcos-4.2.0-x86_64-installer.iso file from this link, constantly receive dracut-initqueue errors.
• The rhcos-4.1.0-x86_64-installer.iso works fine.
• The errors from /run/initramfs/rdsosreport.txt are as follows.

localhost coreos-installer[685]: cat: /tmp/selected_dev: No such file or directory
