are journal files required on slave?

[Klaus Darilion]

Hi!

The default setting of max-journal-size filled my disk. I do have plenty
of zone from KByte to GByte. So I wonder, what would be the perfect size
to configure. So, I wondered - do I need a journal at all? I know the
journal is needed for ixfr-from-differences and DDNS.

But on a server with slave-zone only (fetched by ixfr) - do I need a
journal at all? How can I disable it - by setting the max-size to 0?

Thanks
Klaus
