Hi. Thanks for your quick reply.
Regarding fakeroot, I was really thinking about packages that might rely on fakeroot being present, but in a way not related with dpkg or rules-requires-root, i.e. imagine a package doing this in the build target, either directly or indirectly: fakeroot tar czvf some-artifact.tar.gz sometree My concern here is that by dropping fakeroot from the chroot, we may uncover some missing build-depends, similar to what it happened with tzdata some time ago. I guess the only way to see if there are any packages doing that is by actually trying to build them without fakeroot, so that's what I will probably do and will let you know how it goes... Thanks.
