Checklist

[jepler]

Checklist of things to do before more widely publicizing the image this builds:

• Enable SPI overlay
• install ntpd, ensure systemd-timesyncd is turned off
• any non-warranty-voiding speed tweaks
• a proper apt repository for the linuxcnc and kernel images
• package mesaflash
• package a 2.8ish linuxcnc

Would be nice

• pi3 kernel
• linuxcnc build deps preinstalled?
• enable the right opengl
• inhibit or disable screensaver/screen locking by default

The second iteration image is (sha256sum)

Couple things..
-The screen shouldn't go to sleep on a machine control. (I think) But I haven't figured out how to change that.
-Force_turbo=1 doesn't void the warranty bit. (and I think it still throttles down when too hot)

Hm, himblick uses a program "caffeinate" as a wrapper to disable screensaver. Not sure how to apply that to linuxcnc. Perhaps it's not the right technique anyway. https://www.enricozini.org/blog/2019/himblick/himblick-media-player/ https://manpages.debian.org/buster/caffeine/caffeinate.1.en.html
