I'm working on getting a reliable image for a kiosk style application. Currently one of our big issues is boot stability. Since there's a high likelihood of our computers being hard-reset or losing power, a frozen/stuck boot is a common fault state for us.

To try to counter this, someone suggested making the root partition read-only.

That's fine, but I'm not sure how I can download content onto the device (and keep it there through reboot)

I was thinking of making two partitions, one with the OS and one for file storage. Would this work in OverlayFS? Does this create any issues?

  • Do you need overlayfs for that? Creating a separate partition for the Downloads (or home) directory and mounting root read-only should be enough for that, I think. – muru Jun 06 '18 at 01:09
  • The attractive part of overlayfs is being able to change the underlying system if i want to without too much hassle. – Mike Jenkins Jun 08 '18 at 23:01
  • and remounting root rw is a huge hassle? O.o – muru Jun 09 '18 at 02:09
