Disable MongoDB restart on upgrade (RPM package)

MongoDB RPM packages (provided by official repo.mongodb.org repository, as of version 3.4.1) automatically and unconditionally restart server on package upgrade. This behaviour is hardcoded into postun handler:

if test $1 -ge 1                                                                                                                                                                                                    
then                                                                                                                                                                                                                
  /usr/bin/systemctl restart mongod >/dev/null 2>&1 || :                                                                                                                                                            
fi

This is an inconvenient and dangerous behaviour, especially when you use configuration management tools to set up your servers. For example, I'd like to run a full Ansible playbook to set up my servers first, and then restart MongoDB manually one by one to have full control of the situation.

Is there any way to alter or disable this? Alternative MongoDB packages, maybe? Or some obscure yum/rpm command option to disable scriptlets?

I'm aware that I can switch to simple .tar.gz installation, but this is the last resort.

If you first download the rpm and install it manually using rpm; you can use the --nopostun option:

rpm -Uvh mongodb***rpm --nopostun

from the rpm man page:

  --noscripts
  --nopre
  --nopost
  --nopreun
  --nopostun
  --nopretrans
  --noposttrans
         Don't execute the scriptlet of the same name.  The --noscripts option is equivalent to
         --nopre --nopost --nopreun --nopostun --nopretrans --oposttrans
         and turns off the execution of the corresponding %pre, %post, %preun, %postun %pretrans, and %posttrans scriptlet(s).

afaik yumcannot handle the --nopostun and other flags.
