What is the total size of the package-cache, like du -hs ? Could it be the same size of the difference in image size ? That would mean that the contents of the packages themselves is cached in the image... On 11 Nov 2013, at 10:39, phil@highoctane.be wrote:

Everything loads fine.
But:
with a package-cache/ empty, the final image is: 44.452.060 with a changes file of: 10.831.877
with a primed package-cache (meaning, letting the mczs in place and starting with a fresh image), the final image is: 29.480.912 with a changes file of: 10.830.899
That's quite a huge difference.
I tried again to be sure (fresh image and empty package-cache, then fresh image only) and, weirdly enough, even if the difference in size was the same, the sizes themselves weren't.the same...
44.446.152 - 10.830.899 29.986.284 - 10.831.543
Maybe that's due to a GC occurring differently between the two.
But this gives the impression that one cannot load a base image, apply a configuration, and end up with the same image twice. Weird.
Why is this difference so large in the first place ?
