@hairdyeguy said in Speeding up boot time and the necessary commands:

Tried it along side to disabeling bluetooth and rainbow splash screen + inserting the quiet flag to kernel. Booting time is now 28 seconds!
Are there more things you'd recommend?

The EmulationStation settings I mentioned in my first post - they should speed up dramatically the front-end startup.

Other services that are not strictly needed - raspi-config(?), hciuart (which you don't need if you disabled Bluetooth), rpi-eeprom-update (the Pi zero doesn't have an EEPROM).
You can also disable the swap service (dphys-swapfile) and test, but the Pi 0 has limited memory and swap may be useful if you want to install from source or run other things.

I'm not sure why the dev-mmcblk0p2.device takes so long, maybe the sdcard is not so fast (?).

There may be other - more radical - options

@dreamcastkid Found it! This works completely. It was a MOTD thing. This will get rid of all of that text.

Use command touch ~/.hushlogin

then navigate to the login script
sudo nano /etc/pam.d/login script
#hashtag out the following:
session optional pam_lastlog.so
session optional pam_motd.so motd=/run/motd.dynamic
session optional pam_motd.so noupdate

then navigate to the autologin.conf
sudo nano /etc/systemd/system/getty@tty1.service.d/autologin.conf
Change ExecStart located at [Service] from:
ExecStart=-/sbin/agetty --autologin pi --noclear %I $TERM
To:
ExecStart=-/sbin/agetty --skip-login --noclear --noissue --login-options "-f pi" %I $TERM

Now I am completely rid of any startup text.
