Build(root) an extroot tarball


I'd like to build a minimal image (not x86) with filesystem utilities and extroot stuff, then build a tgz having the root files for the extroot overlay. Is there a way to do so?
The extroot tarball should contain both extra packages and extra configs.
I'm ok for the minimal image, as it is just a pretty basic buildroot usage. The thing I don't know how to produce is the extroot overlay tarball.

My buildroot kungfu is too little to figure out this. Any doc page to do so? Any help would be appreciated.


This question has come up in various forms, but so far I've never seen this achieved. While it might be possible, the honest truth is that the best way to make it work would be to simply script the extroot process and subsequent package installation (this latter part should be trivial provided that your device has internet connecitvity).

Yeah, that was my plan B at the time of posting my message here. I was hoping to reduce the installation steps by prepping everything in buildroot.
All good. Thanks to extroot wiki page the scripting is trivial as well.

Thank you

Yeah... I do the whole process for a few different devices I have extrooted... I repeat the process (largely scripted) for each upgrade. It usually takes less than 10 minutes to do, but I absolutely understand what you were after. I think it might theoretically be possible, but it would probably require more development work than it is worth.
