Read only Root FS UDOObuntu 2.1.4 Minimal

Hello,

I have to do a read only File System for my UDOO QUAD. For the moment I decided to use UDOObuntu 2.1.4 Minimal and try to make it rugged by doing a read only root FS.
Is someone already did this?
Do you know which RW mounts should be mount as tmpfs ?
Do you think I should use another Linux like Yocto or Buildroot instead Ubuntu minimal?

For information, I will need to use Qt5 for GUI and Python.

Regards

 

Armbian Ubuntu version - you can switch to virtual read only root from armbian-config menu.

 

Hello igorpec,
Thank you for your answer. I'll have a look to armbian.
Does it use a tmpfs with initramfs and squashfs, or does it use with overlay? (maybe it's the same thing and I confound as I'm beginner in RO files systems).

 

It's done with overlays - this way: https://spin.atomicobject.com/2015/03/10/protecting-ubuntu-root-filesystem/

 

ok, thank you very much for the information. Really good blog atomicobject , I didn't knew it .
