Bug#859157: multipath-tools: after bootup multipathd timeout on commands - requires daemon restart

[Ritesh Raj Sarraf]

Control: tag -1 +moreinfo

I cannot reproduce this locally in my setup.
My guess is, from your other bug report, that you may have other components
interfering with multipath but I cannot confirm that right now with the limited
information available.
