I meant it doesn't do much more in terms of what it achieves for the user. But we can also just take F18 as the base point, if you like. We're still over 2x as big as that was. > I think some curation on firmware could happen. I think probinson@ mentions > it later in this thread.

We already do a lot of "identifying the firmware necessary for the installer environment", see my earlier mail about all the stuff lorax does here. We've done the easy part, unfortunately. The stuff that's left is stuff that is, in some sense, needed - graphics card and wireless adapter firmwares, mainly. > > > Other obvious things that take up a lot of space: > > > > 1. /usr/lib/locale/locale-archive , from glibc-all-langpacks - this is > > 224M uncompressed.

I'm not sure it can. The "compressed" size is the effective size we're concerned about, because the installer filesystem image is an xz-compressed squashfs. So 11M is already the "effective weight" of this file, I think - if I ran an image build with it removed, it'd probably be ~11M smaller. > > > 2. /usr/lib64/libLLVM-15.so, which is 114M on its own, compresses to > > 23M.
