Thanks,
That helps.
I followed your post: Overlap Docker and Plymouth services boot - #8 by jeremias.tx
and got what I wanted.
Some steps:
No need to do: sudo systemctl edit --full plymouth-quit.service
Create new plymouth-quit.service sudo nano /etc/systemd/system/plymouth-quit.service
Add:
[Unit]
Description=Terminate Plymouth Boot Screen
After=rc-local.service plymouth-start.service systemd-user-sessions.service docker.service
[Service]
ExecStartPre=-/usr/bin/sleep 10
ExecStart=-/usr/bin/plymouth quit --retain-splash
Type=oneshot
RemainAfterExit=yes
TimeoutSec=20
Reboot system
Hope that can help
