When you are doing different things for the input and output archives
then it is better to split serialization into load and save:

#include <boost/filesystem/path.hpp>
#include <boost/serialization/split_free.hpp>

namespace boost { namespace serialization {

template <typename Archive>
void serialize(Archive& ar,
                filesystem::path& p,
                const unsigned int version)
{
     split_free(ar, p, version);
}

template<class Archive>
void save(Archive & ar,
           const filesystem::path& p,
           unsigned int version)
{
     ar << p.string();
}

template<class Archive>
void load(Archive & ar,
           filesystem::path& p,
           unsigned int version)
{
     std::string data;
     ar >> data;
     p = data;
}

}}
