In general, you cannot change the permissions on devices.
The name spaces, rather than permissions, control sharing.
The permission bits on devices serve mainly as documentation
about what you can expect to do with the device. In this case,
acme win provides a /dev/consctl with no permissions because
it doesn't (can't) implement any of the special writes to /dev/consctl.
If you need to use a program that insists on writing to /dev/consctl
you can try running it in a normal rio window.
