Just thought of sharing it to have some suggestion/enhancement on
Varnish upgrade.

Using Ubuntu 10.04 LTS 64-bit, with Varnish 3.0.2. When I tried to
upgrade Varnish to 3.0.3, It seems that it cannot upgrade the Varnish
shared libraries automatically.

   What would you like to do about it ?  Your options are:
    Y or I  : install the package maintainer's version
    N or O  : keep your currently-installed version
      D     : show the differences between the versions
      Z     : background this process to examine the situation
 The default action is to keep your current version.

Delete the /var/lib/varnish manually before the upgrade will do the
trick, but would be better to have it done in automated way :)
