Bug#934491: libelogind0: failing to switch from systemd to sysvinit-core/elogind results in libsystemd.so.0 disappearing

[Mark Hindley]

Simon,

Thanks for this.

I was aware of this in the sense that I know systemd can't be uninstalled whilst
it is PID 1. Most recently this was discussed in #930105 and tagged wontfix.

The only way I have managed to migrate systems reasonably cleanly is to boot
with init=/bin/sh, replace systemd with whatever else and then reboot again. But
as you point out, that is not the obvious migration route that a normal sysadmin
might take.

The problem is that the route recommended in #930105 (et al.) is to first
install sysvinit-core, reboot and then remove systemd. The first step of this
will require removal of almost the entire GUI environment -- something few would
persist with even though it could all be reinstalled later.

These are useful, thank you. I will experiment and see.
