** Description changed:

+ == Rationale ==
+ For some reason /run/resolvconf sometimes (race condition) doesn't exist at the time we try to setup LTSP. This is a bug in its own but is then making a touch /etc/resolv.conf fail in ltsp-client-builder.
+ 
+ The workaround for now is to call mkdir -p /run/resolvconf through in-
+ target, thereby ensuring /run/resolvconf always exists, which should
+ make the touch succeed.
+ 
+ == Test case ==
+ It's unfortunately a race condition, so short of trying a few installs and considering it fixed, there's no trivial way of confirming this.
+ One could try to remove /run/resolvconf on purpose just before ltsp-client-builder is called and see what happens, but that'd require some pretty careful timing.
+ 
+ == Regression potential ==
+ This is a mkdir -p of a directory under /run, so it really shouldn't ever fail.
+ However the fix is just working around a bigger problem and if anything inside the target tries to resolve a hostname, this will still fail as we won't have any DNS servers configured.
+

  The following error occurs during LTSP server installation on hardware
  with Ubuntu 12.04.2 LTS "Precise Pangolin" - Release amd64+mac
  (20130213.1).
  
  Feb 13 11:40:02 main-menu[409]: (process:21643): mount: mounting proc on /target/proc failed: Device or resource busy
  Feb 13 11:40:02 main-menu[409]: WARNING **: Configuring 'ltsp-client-builder' failed with error code 1
  Feb 13 11:40:02 main-menu[409]: WARNING **: Menu item 'ltsp-client-builder' failed.
  
  **This is with amd64+mac and will report the outcome of i386 and amd64
  installations shortly.
  
  == Test case ==
  1) Press F4
  2) Choose LTSP
  3) Install
  (This is a side-by-side installation along with another precise alternate one. Not sure if that's any reason for this)
