CentOS 7 kickstart - Skip media check during unattended installation?

Question

Is there any way to skip the media check screen during unattended text-mode installations of CentOS 7?

I usually install using the minimal ISO, and I've noticed that I need to press ESC once or twice to get out of the ISO's media check.

I don't have mediacheck or rd.live.check specified anywhere in my kickstart file.

Solution

The CentOS ISO images include rd.live.check as a boot command line option. If you haven't rolled your own images, or manually removed this each time you boot, then the media check will occur.

The following appears when booting the CentOS 7.2.1511 netinstall image:

To resolve the problem, tap your up arrow key to select "Install CentOS 7" instead of "Test this media & install CentOS 7".

Running the media check by default has been the thing to do ever since recordable CD-ROMs were a thing. Lots of them were bad, and you didn't want to find out halfway through an installation that you had a coaster.

@cnd Lots of installs take place on a USB stick now, which probably still needs a media check, but I certainly wouldn't want to let it do a media check when doing an installation over iLO with the ISO on my workstation and the server halfway around the world... Unfortunately the default is still to test media in RHEL 8.
