[Bug 1549369] Re: Updating the apparmor manifest and deploying the new code without increasing app version does not trigger apparmor profile update on the device.

[Jamie Strandboge]

I'm not familiar with the click codebase, but I wanted to explicitly
state that when updating the symlink, be sure that you only update the
symlink for the package that is being installed and not all symlinks for
other installed packages. Otherwise all the symlinks's mtimes will be
updated and all policy will be recompiled when an app is installed.

  Updating the apparmor manifest and deploying the new code without

Bug description:
  On Krillin, as of rc-proposed r264,

  modifying the application apparmor manifest and then deploying the
  application to the device *without* increasing the app version will
  not trigger the apparmor profile update.

  As a consequence, the developer is left confused because the app is
  still complaining about apparmor denials even after he modified the
  apparmo manifest and deployed the new .click package.

  Deploying changes to an application without updating its version
  number is a quite common practice, especially while in development
  phase.

  That is why I believe we should fix this bug as soon as possible, to
  make life of developers easier.
