I pinged Aurelien on IRC about this. Let me summarize your answer here: * The relevant maintainer scripts are fragile. Experience has shown that every time one touches them they break. They should be well-tested. * Does the patch actually make libc6 work the way it advertises? * What about libc-bin? * Why not move forward with more testing of more packages before applying this patch? Yes, that makes sense. Let me give a partial answer already. I've performed a number of upgrades from unstable to patched libc packages in buildd-like environments now. The coverage is limited. I've set up a little testing lab to build patched versions of base-files, bash, coreutils, debhelper, debianutils, dpkg, glibc, shadow and util-linux. When installing subsets of essential using these patched packages, few packages fail to install. The failures are base-files, base-passwd, bash, dash, debconf, libc-bin, libpam-modules-bin, libpam-modules, libpam0g, login, mawk, sysvinit-utils, and util-linux. The majority of failures is due to missing patches for debconf. libc-bin is notable here as it will need changes to ldconfig to support this use case. However, very few packages depend on libc-bin. Therefore, I think solving libc-bin at a later time is reasonable. Small steps have been made in various packages: https://salsa.debian.org/pkg-debconf/debconf/-/merge_requests/4 https://salsa.debian.org/debian/shadow/-/merge_requests/10 https://salsa.debian.org/debian/shadow/-/merge_requests/11 https://salsa.debian.org/debian/debianutils/-/merge_requests/5 Guillem Jover resumed up work on dpkg-maintscript-helper and update-alternatives. In any case, I think that this patch does indeed make the library (not libc-bin) work for DPKG_ROOT and I'd prefer libc-bin to be handled in a separate issue. So yeah, we can move forward without this being merged if we really want. Questioning whether this patch blocks progress was a useful thing to do. There will be more fixes. Helmut
