Stdin during rhel 7 bootup (systemd)
Hi All,
I had a startup script (rc3.d/S01getinput) which will accept user inputs during the boot up in console. Basically it will prompt for input. It was working fine in RHEL6.
Now I have migrated to RHEL 7 and script gets executed as part of the boot up process. But it does not prompt for the user input.
How I can stdin during the RHEL7 boot up process ?
Thanks,
Kalai

SYNOPSIS

DESCRIPTION
systemd-ask-password-console.service is a system service that queries the user for system passwords (such as hard disk encryption keys and
SSL certificate passphrases) on the console. It is intended to be used during boot to ensure proper handling of passwords necessary for
boot. systemd-ask-password-wall.service is a system service that informs all logged in users for system passwords via wall(1). It is
intended to be used after boot to ensure that users are properly notified.
See the developer documentation[1] for more information about the system password logic.

parameters.
