Boot-time kernel parameters
- [Instructor] Changing boot time kernel parameters is easy using Tuned's bootloader plugin. Let's add a .custom profile that we created in a previous video with vi. In a terminal I'll type in sudo vi /etc/tuned/customprofile/tuned.conf and hit Enter. Let's add a bootloader section to this. Type a left square bracket, the word bootloader, and then right square bracket. Hit enter, and then we're going to add the command line that we want to add to the boot configuration. Type in cmdline=quiet, and that's it. We'll save this by pressing ESC:x! and hit enter. Now all we have to do to update our grubone or grubtwo config is to switch to this profile using tuned-adm. Type in sudo tuned-adm profile customprofile and hit Enter. Note that these are boot time parameters. You will not see the change until you've rebooted your system.
