This update will fix some rough edges around systemd integration. mlocate-updatedb.timer unit is started after the package installation. Also, systemd unit wrapping updatedb doesn't declare explicitly Type= option, hence type simple is assumed and systemd will not wait for completion of the service. This should fix the issue when udpatedb was triggered by timer on system boot and updatedb was taking too long and blocking user login.
