libpam-systemd depends systemd-sysv. libpam-systemd also depends

systemd which must be removed first.
However, to get systemd uninstalled we first have to replace systemd-sysv with
sysvinit-core (leaving systemd installed) and reboot. systemd and elogind
conflict so we cannot use libpam-elogind to replace libpam-systemd *yet*.
This is the point we need a transitional package to temporarily satisfy
libpam-systemd's systemd-sysv dependency whilst the system is rebooted.
After reboot, systemd is no longer PID1 so can be removed and we can then
complete the transition replacing libpam-systemd with libpam-elogind, removing
systemd and installing elogind.
I hope that is clearer.
Kinda, sorta.
I think it's consistent with my experience of migrating buster to beowulf.
At the time, I was ready to say that it can't be done and we shouldn't
support it, but I did succeed after two days of messing with it. Nice to
see you have a way to make it work smoothly.
