Beginners help for fast boot project

[tallyho]

Hello, I am relatively inexperienced with linux, and am embarking on a project for my raspberry pi zero.

I would like to have a raspberry pi zero boot to a headless application as quick as possible. My plan so far is to..

1. Use Tiny Core Linux. If its small, it has to be fast??
2. Use "Core" as the only thing I want to do is launch the application.
3. Make it fast to boot by trying these instructions http://himeshp.blogspot.com/2018/08/fast-boot-with-raspberry-pi.html

How does my plan look?

thanks

The instructions in the link you provided won't work for TC.

We don't use [systemctl] as TC does not support systemd by design.

To boot the system fast, you can try remastering the filesystem image. (ex: rootfs-VERSION.gz)

What applications are you going to run ?

piCore may not have the extensions you'll need.

What always adds time to boot is device recognition.  Drives and network devices are notoriously slow.  It really depends on what you are trying to do....
