So, it looks like anaconda has zram support and enables it if there's 2GB memory or less or you pass 'inst.zram=1' on the boot line. How does this interact with that? Could we perhaps get both of them to use the same setup so we don't have multiple places we enable this? Perhaps it's worth enabling on other arches as well? Finally I wonder if the 2GB limit is still right? Should we increase that? I have heard of lot of people say recent releases need more memory, this might help that out? kevin
