I just modified my grub kernel command line to add the consoleblank=0 parameter. That isn't the problem. First consoleblank is the kernel screensaver and according to the documentation it kicks in after 15 minutes by default. What I'm doing for testing is: 1) systemctl set-default foo.target 2) foo.target.wants/foo.service 3) foo.service invokes /mydir/foo.sh 4) /mydir/foo.sh consists of echo "foo.sh starting to sleep" logger "foo.sh starting to sleep" sleep 10 echo "foo.sh after sleep" logger "foo.sh after sleep" systemctl isolate multi-user.target
What I see is a few kernel driver start up messages. Then the console screen blanks for about 10 seconds. Then multi-user boot completes. What I'm hoping to see is: foo.sh starting to sleep foo.sh after sleep -----Original Message----- From: systemd-devel [mailto:systemd-devel-boun...@lists.freedesktop.org] On Behalf Of Tomasz Torcz Sent: Wednesday, August 12, 2015 12:26 PM To: systemd-devel@lists.freedesktop.org Subject: Re: [systemd-devel] Console screen blanks while long running service executes On Wed, Aug 12, 2015 at 06:41:35PM +0000, Harry Goldschmitt wrote: > I have a target that runs a service during boot on CentOS 7.1.
