Package: systemd Version: 247.3-6 Severity: important Dear Maintainer,
I'm upgrading my systems periodically using: DEBIAN_FRONTEND=noninteractive apt-get -y -q -o Dpkg::Options::=--force-confold dist-upgrade The systemd debian package will silently overwrite /etc/sysctl.d/99-sysctl.conf with a symlink to /etc/sysctl.conf If a user changes 99-sysctl.conf to a regular file and puts some changes into that file, these changes will get lost during the upgrade, thus possibly breaking systems which depend on those changes. I have verified this occurs in debian buster and bullseye. The current experimental package 249.2-1 also includes this symlink in its systemd.links file. -- Package-specific info: -- System Information: Debian Release: 11.0 APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 5.10.0-8-amd64 (SMP w/32 CPU threads) Kernel taint flags: TAINT_PROPRIETARY_MODULE, TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages systemd depends on: ii adduser 3.118 ii libacl1 2.2.53-10 ii libapparmor1 2.13.6-10 ii libaudit1 1:3.0-2 ii libblkid1 2.36.1-7 ii libc6 2.31-12 ii libcap2 1:2.44-1 ii libcrypt1 1:4.4.18-4 ii libcryptsetup12 2:2.3.5-1 ii libgcrypt20 1.8.7-6 ii libgnutls30 3.7.1-5 ii libgpg-error0 1.38-2 ii libip4tc2 1.8.7-1 ii libkmod2 28-1 ii liblz4-1 1.9.3-2 ii liblzma5 5.2.5-2 ii libmount1 2.36.1-7 ii libpam0g 1.4.0-9 ii libseccomp2 2.5.1-1 ii libselinux1 3.1-3 ii libsystemd0 247.3-6 ii libzstd1 1.4.8+dfsg-2.1 ii mount 2.36.1-7 ii systemd-timesyncd [time-daemon] 247.3-6 ii util-linux 2.36.1-7 Versions of packages systemd recommends: ii dbus 1.12.20-2 Versions of packages systemd suggests: ii policykit-1 0.105-31 ii systemd-container 247.3-6 Versions of packages systemd is related to: pn dracut <none> ii initramfs-tools 0.140 ii libnss-systemd 247.3-6 ii libpam-systemd 247.3-6 ii udev 247.3-6 -- Configuration Files: /etc/systemd/journald.conf changed [not included] -- no debconf information
