Since this is the first cgroupfs-mount update since 2017 (which predates elogind's arrival in Debian) I suspect it has always been there, just uncovered by the cgroupfs-mount NMU. My gut reaction is that cgroupfs-mount shouldn't be unmounting and remounting cgroups on upgrade and it needs some dh_installinit magic in d/rules. Mark

Package: cgroupfs-mount Severity: serious Version: 1.4+nmu1 Hi, cgroupfs-mount fails to upgrade from 1.4 to 1.4+nmu1 for me (elogind + sysvinit) as follows: Setting up cgroupfs-mount (1.4+nmu1) ... Unmounting cgroupfs hierarchyumount: /sys/fs/cgroup/elogind: target is busy. invoke-rc.d: initscript cgroupfs-mount, action "restart" failed. dpkg: error processing package cgroupfs-mount (--configure): installed cgroupfs-mount package post-installation script subprocess returned error exit status 1 Trying to remove the package fails in the same way: Removing cgroupfs-mount (1.4+nmu1) ... Unmounting cgroupfs hierarchyumount: /sys/fs/cgroup/elogind: target is busy. invoke-rc.d: initscript cgroupfs-mount, action "stop" failed. dpkg: error processing package cgroupfs-mount (--remove): installed cgroupfs-mount package pre-removal script subprocess returned error exit status 1 Stopping elogind before trying to unmount /sys/fs/cgroup/elogind solves the issue. P.S.: Given that Christian's NMU doesn't even touch the maintainer scripts, I suspect that this issue is also present in version 1.4. I though didn't notice it before then, so it might be related to recent elogind changes, hence Cc'ing the Debian Init System Diversity Team, too. -- System Information: Debian Release: trixie/sid APT prefers unstable APT policy: (990, 'unstable'), (600, 'testing'), (500, 'unstable-debug'), (500, 'buildd-unstable'), (110, 'experimental'), (1, 'experimental-debug'), (1, 'buildd-experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 6.7.12-amd64 (SMP w/8 CPU threads; PREEMPT) Locale: LANG=C.UTF-8, LC_CTYPE=C.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: sysvinit (via /sbin/init) LSM: AppArmor: enabled
