The /var/lib/dirsrv is owned by the 389-ds-base RPM and it's generally assumed that the folder will always exist as long as the RPM is installed.

%dir %{_localstatedir}/lib/%{pkgname}

Some applications such as IPA are using this folder various purposes (e.g. home directory for DS user, storing boot.ldif). The problem is currently the remove-ds.pl will delete this folder if it's removing the last DS instance.

# remove /var/lock/dirsrv & /var/run/dirsrv if this was the last instance
if(!<$pkglockdir/*>){
    rmdir $pkglockdir;
    rmdir $pkgrundir;
    rmdir $pkglibdir;
}

This could create problems to other applications (e.g. IPA installation will fail) since the above assumption will no longer be true. The remove-ds.pl should not remove any folder created by the RPM. The folder should only be removed when uninstalling the RPM.

The setup-ds.pl currently will create the /var/lib/dirsrv folder, but it shouldn't be necessary since the folder is created automatically during RPM installation.
