    "summary": "* PACKAGING FIX: rsync daemon default group on stock Ubuntu/Debian (ELSR-8050) - the daemon's compile-time NOBODY_GROUP was resolved to \"nobody\" by the focal build chroot's /etc/group, but stock Ubuntu/Debian have only \"nogroup\", so daemon modules with no explicit gid were rejected with \"@ERROR: invalid gid nobody\" (test_daemon / ELSR-8050) - debian/rules: build with rsync's own --with-nobody-group=nogroup configure option so the compile-time NOBODY_GROUP default is baked as \"nogroup\" regardless of the build chroot, matching the stock Ubuntu/Debian rsync build (fixes modules with no explicit gid) - debian/patches/rsync-daemon-nobody-group-fallback.patch: in the daemon's add_a_group() resolve a \"nobody\" group to \"nogroup\" at runtime when the host has no \"nobody\" group, so a module that explicitly sets \"gid = nobody\" is also honoured on stock Ubuntu/Debian instead of being rejected with \"@ERROR: invalid gid nobody\"; any other unresolvable group is still rejected - upstream: configure.ac AC_ARG_WITH(nobody-group) https://github.com/RsyncProject/rsync/blob/v3.1.3/configure.ac#L142-L157 Debian bugs #144570 (https://bugs.debian.org/144570) and #25299 - ELSR-8050",
