You seem to have completly missed my point. This function is used in two binaries in the whole tree. My previous email provides a grep of the entire CVS tree to show which ones. All other users of this function using it by calling the mapdevfs program. To move this function out of libd-i, all of one program (yaboot-installer) would need a trivial modification. > the function needs nearly 1kb code, a binary for this needs at least > 8kb. moving them out don't save anything. By your numbers, it saves 1 kilobtye on the boot media. That is a significant part of some of our boot media, and a *very* significant part of the free space on some of them. A binary for this function already exists: mapdevfs. Moreover, that binary has no reason to go on the boot media, since all users of it run after the retreivers are configured. This was one example, shall I find some more? Or do you want to account for why libdebian-installer *doubled* in size in its last release? Multicall binaries that call back to very special-purpose functions in a large monlithic library is not an appropriate design for d-i. You seem to be promoting both. In my latest release, I moved the di-utils-shell part of di-utils out of the multicall binary, which is not included on the initrd, and turned it into the postinst of the package. If I had left it in the multicall binary instead, and included that on the initrd, it would have wasted ~1.5k with its layers and layers of redirection. (Incidentially, my change also fixed the menu item.) It semes to me that you don't know how to think about saving space in d-i. And please stop committing things that are broken. -- see shy jo
