View Full Version : [SOLVED] How to remaster a "desktop-less" system.

Hi.

I need to replicate my current system to other PCs. This system does not have a standard desktop. It is a Lubuntu Minimal install, with re-built kernel, some packages, settings and tweaks added after installation. The process should allow people without special knowledge to complete the installation quickly, by following some "easy" steps.

So I searched for remastering tools and tested Remastersys, but it seems it needs an "standard" installation as base system, as I got the error message:


Error Remastersys:

Lightdm not setup properly. You must set your default desktop with lightdm prior to remastering

Beyond that, I don't know how complete this task. So I hope I could get some tips and references in order to make this task. My concrete questions are:



Is there a tool or procedure that I can follow in order to get an ISO from my current system, so it can be installed easily on other PC.
The target PC's are going to have flash drives as main storage, and are susceptible to be powered off without a proper shut down. Is there a way to mitigate this, like making the resulting ISO a "RAM filesystem installation?.


Thanks for reading, and best regards.

Although you only need to know how to create an ISO of your current install. The other option is an OEM install. There is info available about that and I think you can choose that option using the mini.iso, the ISO you used originally. Interesting support question, though, that has me thinking some more ... :-k

Hi @Bucky Ball. Clonezilla has proved to be a superb piece of software. "OEM installer" would be more usefull if "Prepare for shipping" button generated an installing iso. But I think that Clonezilla is all what I need. Now I only need to know how can I configure the installation to be as "read-only" as possible, so I think I will start another thread on this subject (if there is not a thread on this same mather already).

Once again thanks for your help.

No problem, and yea, Clonezilla is great. Glad it suited and good luck with the new thread and everything else. Enjoy! ;)

Just wondering if you could do an OEM install up to a certain point, THEN create an ISO of it using Clonezille when you have it how you want. Just a thought. :-k
