@eseelke The short answer is, it isn’t going to happen. The WIM files are windows centric. You have to remember that FOG is based on linux, and the engine that writes the image files to disk [i.e. FOS] is linux based. FOG/FOS uses partclone to capture image files, that can be expanded or compress dynamically (to a certain point) based on the size of the target media. I do agree that there would be value in integrating the WIM file format into FOG, but not enough for the developers to spend their time on. FOG has a very fast working solution today.
But, yes, if you want to tweak the golden image you can’t do it from the captured file like you can with a WIM format. The other thing you have to be aware of is that FOG supports more operating systems than just windows. The wim format is (very) windows focused.
Well after the above response I did a little google-fu and found there are linux libraries that support reading and writing wim files. ref: https://wimlib.net/ Briefly looking at the document it appear it is possible. I guess I’ll leave it up to the developers if they are interested, possibly for FOG-too. As for me my initial reaction still stands.
yes I agree with you that there are Linux libraries that support the reading and writing of wim files but it remains insufficiently frankly
