dscreate creates and starts an instance successfully. {start,stop,status}-dirsrv commands are not functional as in previous build:

# status-dirsrv 
● dirsrv.target - 389 Directory Server
   Loaded: loaded (/usr/lib/systemd/system/dirsrv.target; disabled; vendor preset: disabled)
   Active: inactive (dead)
No instances found in /etc/sysconfig
# stop-dirsrv 
No instances found in /etc/sysconfig
# start-dirsrv 
No instances found in /etc/sysconfig

But at least systemctl commands work now to start/stop instances.
