Indeed, latest git works much better :)

Can you try with latest git? We did some improvements on the systemd configure parts.

Looking at config.log, there is #define HAVE_LIBSYSTEMD 1
But "Type=notify" does not appear
My systemd is version 248

I don't know then. It works for me and I just tried it again. The only reason it would fail would be that HAVE_LIBSYSTEMD is not defined, so it would not be using libsystemd for notify support.

You can tell from the "Status" line that it's using Type=notify.

Yes, I do run autogen.sh after every "git pull"

The current autoconf code is bit buggy, but if you do indeed have libsystemd-dev installed it should do the right thing and will work with systemd even if you have Type=notify.

This has been actually tested, so if it's not working, then something else is wrong.

Did you remember to run ./autogen.sh after pulling from git to make sure you get new configure script?

Yes systemd is installed (and the "dev" files as well)

This is because you are not compiling with libsystemd-dev installed. I guess we need to make some service template that use type simple when you don't use libsystemd.

Yes, it seems fixed with this patch :)

Another bug with git, is the "type=" in systemd is switched from "simple" to "notify". The later does not work and reverting to "simple" does work

chroot= does not resolve the issue
I have "chroot = login" in my conf

Thanks!

The chroot was needed to get the core dump.

Can you try if this does fix the crash?

Subject: [PATCH] login-common: Fix handling destroyed_clients linked list

The client needs to be removed from destroyed_clients linked list before
it's added to client_fd_proxies linked list.
