[LEDE Bugs]

A new Flyspray task has been opened.  Details are below.

Summary - leftover printf's in the new opkg (since Feb 20)
Task Type - Bug Report
Category - Base system
Status - Unconfirmed
Assigned To - 
Operating System - All
Severity - Very Low
Priority - Very Low
Reported Version - Trunk
Due in Version - Undecided
Due Date - Undecided
Details - current LEDE opkg seems to have some leftover printfs

Example:
  root at wifi-ap:~# opkg list-upgradable
  alloc item for pkg=0x7e2ab0
  alloc item for pkg=0x7c8900
  alloc item for pkg=0x7dace0
  [...]
  alloc item for pkg=0x7def10
  alloc item for pkg=0x7dcdd0
  alloc item for pkg=0x7d4900
  base-files - 172-r3554-f66a0c93b3 - 172-r3558-19720a6f03

Now, this is easily "fixed" with a 
  opkg list-upgradable | grep -v 'alloc item'
but a) it's still annoying, and b) should be a very quick fix

Don't know what commands this applies to (besides list-upgradable), but a quick recursive grep should probably show the extent of this inconvenience.
