How to disable plymouth services

Unnesessary services which makes computer boot and stop slower.

Plymouth is an application that runs very early in the boot process (even before the root filesystem is mounted!) that provides a graphical boot animation while the boot process happens in the background.

1. Check if plymouth services are on

sudo service --status-all | grep plymouth

2. Disable services

systemctl stop plymouth-quit-wait.service
systemctl disable --now plymouth-quit-wait.service
systemctl mask plymouth-quit-wait.service

systemctl stop plymouth-read-write.service
systemctl disable --now plymouth-read-write.service
systemctl mask plymouth-read-write.service

systemctl stop plymouth-start.service
systemctl disable --now plymouth-start.service
systemctl mask plymouth-start.service

An alternate way is disable via sudo

sudo systemctl stop plymouth-quit-wait.service
sudo systemctl disable --now plymouth-quit-wait.service
sudo systemctl mask plymouth-quit-wait.service

sudo systemctl stop plymouth-read-write.service
sudo systemctl disable --now plymouth-read-write.service
sudo systemctl mask plymouth-read-write.service

sudo systemctl stop plymouth-start.service
sudo systemctl disable --now plymouth-start.service
sudo systemctl mask plymouth-start.service
