Subject: [RFC PATCH v2 08/13] sysrq: Disable bootsplash on SAK
Date: Wed, 13 Dec 2017 20:47:50 +0100
Message-ID: <20171213194755.3409-9-mstaudt@suse.de> (raw)
In-Reply-To: <20171213194755.3409-1-mstaudt@suse.de>

When the user requests a clean TTY via the SAK SysRq, that means he
really wants to use the console.

Let's disable the bootsplash, even if the request is not on a VT, as
the user probably knows what he's doing and it's more helpful to get
out of his way.
