Bug#734794: 734794 kpartx: partition mapping deletion broken

[Sebastian Pipping]

I can confirm that kpartx needs "sleep 2" /after/ adding or removing 
partitions before running some other command that assumes the partitions 
are now gone (or in place).  My guess is that something needs to 
propagate and kpartx could either wait for that change to happen before 
quitting or not, and the current code does not.

If this bug report is about sleeping needed after unmount before kpartx: 
no idea.  However, the mentioned

   umount "[..]/etc/resolv.conf"

looks odd to me, since I suppose that to be a file, not a mount point.

Best, Sebastian
