Package: systemd Version: 232-25+deb9u1 Severity: normal systemd-sysv-install uses `ROOT` variable from environment when not set via `-r` and tries to execute update-rc.d chrooted to the content of this variable.
I'm am a bit unsure whether or not this really is a bug, but since it was a total surprise for me when I found the cause of the issue and I did not find any documentation about this behaviour, I think this is a bug. *Expected behaviour I didn't see* root@Klappspaten:/# systemctl enable ssh Synchronizing state of ssh.service with SysV service script with /lib/systemd/systemd-sysv-install. Executing: /lib/systemd/systemd-sysv-install enable ssh Created symlink /etc/systemd/system/sshd.service → /lib/systemd/system/ssh.service. *Unexpected behaviour I saw* When ROOT is e.g. set to /dev/sda1, this issue occurs: root@Klappspaten:/# systemctl enable ssh Synchronizing state of ssh.service with SysV service script with /lib/systemd/systemd-sysv-install. Executing: /lib/systemd/systemd-sysv-install enable ssh chroot: cannot change root directory to "'/dev/sda1'": No such file or directory *Steps to reproduce the problem* Simply set the environment variable and try to enable a service that is also available as SysV-Init-Script root@Klappspaten:/# export ROOT=/dev/sda1 root@Klappspaten:/# systemctl enable ssh Synchronizing state of ssh.service with SysV service script with /lib/systemd/systemd-sysv-install. Executing: /lib/systemd/systemd-sysv-install enable ssh chroot: cannot change root directory to "'/dev/sda1'": No such file or directory *Possible solution* ROOT should be initialized with an empty value before reading command line options. *References* https://github.com/systemd/systemd/issues/8180 https://salsa.debian.org/systemd-team/systemd/blob/master/debian/extra/systemd-sysv-install -- Package-specific info: -- System Information: Debian Release: 9.3 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 4.9.0-5-amd64 (SMP w/2 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages systemd depends on: ii adduser 3.115 ii libacl1 2.2.52-3+b1 ii libapparmor1 2.11.0-3 ii libaudit1 1:2.6.7-2 ii libblkid1 2.29.2-1 ii libc6 2.24-11+deb9u1 ii libcap2 1:2.25-1 ii libcryptsetup4 2:1.7.3-4 ii libgcrypt20 1.7.6-2+deb9u2 ii libgpg-error0 1.26-2 ii libidn11 1.33-1 ii libip4tc0 1.6.0+snapshot20161117-6 ii libkmod2 23-2 ii liblz4-1 0.0~r131-2+b1 ii liblzma5 5.2.2-1.2+b1 ii libmount1 2.29.2-1 ii libpam0g 1.1.8-3.6 ii libseccomp2 2.3.1-2.1 ii libselinux1 2.6-3+b3 ii libsystemd0 232-25+deb9u1 ii mount 2.29.2-1 ii procps 2:3.3.12-3 ii util-linux 2.29.2-1 Versions of packages systemd recommends: ii dbus 1.10.24-0+deb9u1 ii libpam-systemd 232-25+deb9u1 Versions of packages systemd suggests: pn policykit-1 <none> pn systemd-container <none> pn systemd-ui <none> Versions of packages systemd is related to: pn dracut <none> ii initramfs-tools 0.130 ii udev 232-25+deb9u1 -- Configuration Files: /etc/systemd/logind.conf changed [not included] -- no debconf information
