Package: obs-build Tags: upstream X-Debbugs-Cc: unit...@debian.org Hi,
obs-build has its own implementation of debootstrap in init_buildsystem. Unlike other implementations, it does not ensure that packages from the essential set have been configured before unpacking non-essential packages. The Debian policy requires that essential packages have to work at all times after having been configured at least once. Since non-essential packages may assume presence of essential in their Pre-Depends, essential packages must be configured before unpacking non-essential packages. obs-build's implementation does not ensure this property. We can see this in e.g. https://build.opensuse.org/package/live_build_log/home:unit193/certbot-dns-porkbun/Debian_Testing/x86_64 where essential package bash is installed after non-essential package python3-cffi-backend. The current work on /usr-merge heavily relies on this property. One of the next steps is adding the aliasing symlinks to base-files. If any non-essential package with aliased files is installed before base-files, the aliasing links will be lost and the created chroot will not work at all. I think the property expected here is reasonable and the bug resides with obs-build. In particular, it is a bug that also affects upstream and the upstream deployment at build.opensuse.org. Helmut
