Description Jan Pazdziora 2019-09-02 08:16:16 UTC 
Description of problem:

Running ipa-server-install on Fedora rawhide with Python 3.8, I now see
SyntaxWarning: "is not" with a literal. Did you mean "!="?

I did not see it on Fedora 30 but maybe it's just because Python there was less strict about warning.

Version-Release number of selected component (if applicable):

python3-lib389-1.4.1.6-1.fc32.2.noarch

How reproducible:

Deterministic.

Steps to Reproduce:
1. Run ipa-server-install.

Actual results:

Configuring directory server (dirsrv). Estimated time: 30 seconds
  [1/44]: creating directory server instance

Starting installation...
Created symlink /etc/systemd/system/multi-user.target.wants/dirsrv → /usr/lib/systemd/system/dirsrv@.service.
/usr/lib/python3.8/site-packages/lib389/dirsrv_log.py:148: SyntaxWarning: "is not" with a literal. Did you mean "!="?
  if timedata['nanosecond'] is not '':
Opening SELinux policy "//etc/selinux/targeted/policy/policy.31"

Allocate local instance <class 'lib389.DirSrv'> with ldapi://%2fvar%2frun%2fslapd-EXAMPLE-TEST.socket
  [2/44]: configure autobind for root
  [3/44]: stopping directory server
  [4/44]: updating configuration in dse.ldif
