Question: read-only root filesystem

[cashpipeplusplus]

I'm trying to modify pi-gen to create an image which mounts / and /boot read-only. This means, for example, removing resize2fs_once. In a nutshell, I'm trying to take the steps in this article and do them at generation time so that the system is read-only from the very first boot.

Has anyone tried this, or am I in new territory? I'm sure I'll get it working eventually, but I wanted to see if anyone has any experience here before I spend too much time hacking away at it.

Looks like there isn't anybody else doing this. I'll close this since it's not actually an issue.

[cashpipeplusplus]

Fair enough. For what it's worth: joeyparrish@b3cfadd#diff-c59b8b8fa77cc3c4ea5682ccf394fe53

Also, is there a better place for me to ask questions? A mailing list or forum or something that would be preferable to github's issue tracker?

[XECDesign]

pi-gen doesn't exactly have an active user base to justify a mailing list or a forum. I am happy to answer questions here, but if I don't have an answer and nobody else chimes in, I will close the issue after a while.

I'd definitely use this feature if it were available. I'll try to work @cashpipeplusplus' existing work into a PR with an option controlled by the config file. Is that something that you'd consider merging?

[cashpipeplusplus]

JFYI, if read-only were to be an option, there would be better ways to do it than what I did in my fork. For example, in my fork, I made it a goal replace stage 3 and leave the rest as-is, to make rebasing easier. That means I'm undoing certain parts of earlier stages, rather than changing those stages themselves.

[XECDesign]

The idea is that the stages themselves are separate from build system. The stages provided here are a starting point for people who want to customise the official raspbian image for their needs or to track development and see upcoming changes.

I don't see how a read only option in config fits in with the above. I think it works best as a fork.
