`C:\\oem\install.bat` not executing

[michael-sola]

Operating system

Debian GNU/Linux trixie/sid

Description

Following these instructions, I mounted an install.bat script to the container's /oem directory:

kubectl exec test-windows-node-89bdbd548-swvdr -- ls /oem
install.bat

However, inside Windows it shows up as a directory:

ls C:\\oem

..2024_07_31_21_47_38.5111193299

The batch file is inside the directory, but the script never executes.
