I hope I did this maillist reply correctly. I am doing it with webmail,
not an email client.
libpam-systemd depends systemd-sysv. libpam-systemd also depends
systemd. Devuan's libpam-elogind provides libpam-systemd but conflicts
with
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.
I can get the general grasp of this information as I think a similar shim
was used in devuan when it was first forked.
What I found to get sysvinit-core installed was to
-boot into the debian install, and before changing the sources list to
point to devuan,
-run "apt install sysvinit-core"
then, alter the sources.list to point to beowulf and,
"apt update"
"apt upgrade"
"reboot"
No errors were noted and upon a reboot, sysvinit is running as PID1 and the
migration can continue in a manner similar to what it has been in the past.
Trying to install sysvinit-core after the sources.list pointed to beowulf
caused many problems and I never could get it done that way.
I documented my test migration of a buster Xfce install at:
https://dev1galaxy.org/viewtopic.php?pid=17716#p17716
You did not try the following order:
- modify sources.list
- apt-get update
- apt-get install devuan-keyring
- apt-get install sysvinit-core
- reboot
- apt-get upgrade
