void	fs::blocking::RewriteFileContents (const std::string &path, std::string_view contents)
	Rewrite file contents synchronously.

void	fs::blocking::RewriteFileContentsFSync (const std::string &path, std::string_view contents)
	Rewrite file contents synchronously and call `fsync`

void	fs::blocking::SyncDirectoryContents (const std::string &path)
	flushes directory contents on disk using sync(2)

void	fs::blocking::Rename (const std::string &source, const std::string &destination)
	Renames existing file synchronously.

void	fs::blocking::RewriteFileContentsAtomically (const std::string &path, std::string_view contents, boost::filesystem::perms perms)
	Rewrite file contents atomically.

void	fs::blocking::Chmod (const std::string &path, boost::filesystem::perms perms)
