Summary0017461: systemd-239-30 package prevents some units from stopping
DescriptionThe postgresql unit installed in the postgresql:9.6 package on centos 8.2 fails to stop when using systemd-239-30 and running in an LXD container. This issue does not appear with systemd-239-18 and was introduced with the newest package release. We're having this issue with the Centos 8 LXD image.

Some other systemd services that we write and install in /etc/systemd/system/ also fail, but I mention postgres here because it's an easily reproducible case.

There were 256 patches in the package for systemd-239-18 and 360 in systemd-239-30, so I assume the issue was introduced in a patch between 257 and 360.

To reproduce: install postgres, initialize the database, start postgresql. After this, postgresql will not stop. The state of the systemd service is stuck in 'deactivating' (final-sigkill), even though all processes started by systemd (postmaster, postgresql-check-db-dir, and postgres itself) are dead according to systemd and according to `ps`.
Steps To ReproduceWe create the container with `lxc init images:centos/8 centos8box`.

[ now, inside the container ]

$ dnf install @postgresql:9.6
[...]

$ su postgres -c "/usr/bin/initdb -D /var/lib/pgsql/data -E UTF8"
[...]

$ sudo systemctl start postgresql
[...]

$ sudo systemcl stop postgresql
[ this hangs forever ]

First I run docker container on the host -
 
# docker run --privileged -dit --name pgdg centos:8.2.2004 /sbin/init

Then inside the container, I run the commands given below -

# yum -y install glibc-langpack-en glibc-locale-source
# localedef -i en_US -f UTF-8 en_US.UTF-8

# dnf install https://download.postgresql.org/pub/repos/yum/reporpms/EL-8-x86_64/pgdg-redhat-repo-latest.noarch.rpm

# dnf -qy module disable postgresql

# dnf install postgresql12-server

# /usr/pgsql-12/bin/postgresql-12-setup initdb

# systemctl enable --now postgresql-12

Postgresql starts at this point...

However, when I try to stop it, it just hangs -

# systemctl stop postgresql-12 (hangs)

I also have this problem with centos 8 lxd container or centos 8 proxmox container. The problem clearly come from systemd-239-30 but I really do not know how to track this problem down.

Other than downgrading systemd or CentOS, a workaround is to wait for all child processes to end in the main process:

#!/usr/bin/env python3
import time
import os

pid = os.fork()
time.sleep(3600)
if pid:
    os.wait()

I have just verified and it is still the issue with Centos 8.4 (systemd 239-45)
