Provided the dependency is dynamically linked, you can find everything running against an old version of the .so after it's been updated by using the 'checkrestart' command. A combination of unattended-upgrades and periodic checkrestart runs makes my life as a debuntu admin much easier. Note: Yes, I know how many environments this doesn't apply to. But if one person whose environment it does apply to discovers the joy of 'checkrestart' as a result of this comment, it was still worth typing out :D
