Subject: [RFC 06/14] bootsplash: Disable on SysRq SAK
Date: Wed, 25 Oct 2017 14:45:54 +0200	[thread overview]
Message-ID: <20171025124602.28292-7-mstaudt@suse.de> (raw)
In-Reply-To: <20171025124602.28292-1-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.
