Bug#504760: s390 installer doesn't work on 3215 console running as a VM guest
The latest version of the installation program for the s390 architecture
doesn't work when running on a 3215 virtual console as a guest of z/VM.
In this installation method, the installer performs some initial steps,
such as configuring the network device and configuring the network, while
using the 3215 virtual console. Then the installation switches to a
network console (ssh session) for the rest of the installation. The
trouble is that the installer seems to be treating the 3215 virtual console
as an ANSI terminal. I see a bunch of stuff which appears to be ANSI
escape sequences. This used to work, but something broke it. The
installer must use a line-mode interface while running on the 3215 virtual
console. I cannot get past this.
