Code review comment for lp:~achiang/ubuntu-nexus7/valgrind-ubuntu-dbg-packages

Right, so for permanent installation I indeed recommend installing -dbg only, not ddebs. For the "full" symbol experience the ddebs should be installed only temporarily (they are not very stable on upgrades and also take a ton of space), so something similar like apport-retrace ("apport-valgrind package" or so) would be more appropriate, if the need arises.
