Bug#1101698: Execution of systemctl in preinstall script can cause problems if libsystemd-shared is already upgraded

[Jan Naumann]

Package: systemd
Version: 257.4-4
Severity: serious

Dear maintainers,

in version 257.4-4 the handling of tmp.mount has been moved from the
systemd.postinst to the systemd.preinst script. In the code there is a call to
systemctl which is executed before upgrading the package.

This is problematic since currently the package libsystemd-shared could be
upgraded before the execution of the preinst script and therefore the shared lib
already jumped to a new major version.
The execution of the old systemctl binary will fail afterwards since it depends
on the old version of the library.

In summary this change will likely break upgrades to a new major version.

Thank you for all your work and best regards,
Jan Naumann
