I think people are overestimating their government's control over a zombie outbreak. One bite is all it takes to be infected. The virus would spread at a very fast rate. The only procedure they could take is to quarantine a whole city, and then twiddle their thumbs hoping it would go away. Zombies are relentless, and they have no emotions. They cannot be reasoned with.
This thread also said "Zombie Apocalypse" as in, the whole world is infected and humanity is being driven to extinction. All the governments in the world would dissolve and go into hiding, it would be up to the individual to survive by their own instincts for a long time, from as little as a few years to maybe 20. Therefore, the most logical course of action would be to set up a life on an isolated island that humans did not inhabit. This way, there will be very few zombies to contest with. You will need to have a lot of natural food sources though and live in a similar style to our prehistoric ancestors. Any firearms should be salvaged and used in a very conserved fashion. You should also be ready for pirates and bandits attacking you. Keeping everyone in good shape and trained with weapons would also be a must. After a few years, you should send a scout party to check if zombies have decayed out of existence yet. If the zombie populace has dissolved, now would be the time to set up a new government and civilization.
Needless to say, surviving an outbreak to this scale would be quite difficult.
