What about doing this as a three steps operation? 1. install sysvinit-core; that removes systemd-sysv but nothing else systemd related 2. reboot; init should now be sysv init 3. install libelogind0 libpam-elogind elogind Souldn't that work? But some stuff needs to be addressed first.

Bug #925344 (filed on Sat, 23 Mar 2019 13:33:24 +0000, 6 month ago) needs to be resolved in a speedy manner. But, AFAICS, no progress was made since :( Looking at one of the other packages, udisks2, I see direct and indirect dependencies to systemd: ,---- | Depends: dbus, libblockdev-part2, libblockdev-swap2, | libblockdev-loop2, libblockdev-fs2, libpam-systemd, parted, udev, | ^^^^^^^^^^^^^^ | libacl1 (>= 2.2.23), libatasmart4 (>= 0.13), libblockdev-utils2 (>= | 2.20), libblockdev2 (>= 2.20), libc6 (>= 2.7), libglib2.0-0 (>= 2.50), | libgudev-1.0-0 (>= 165), libmount1 (>= 2.30), libpolkit-agent-1-0 (>= | 0.99), libpolkit-gobject-1-0 (>= 0.101), libsystemd0 (>= 209), | ^^^^^^^^^^^ | libudisks2-0 (>= 2.8.3) `---- Those need to be addressed too.
