dnsmasq cache

[samuelstj]

Alguem sabe como eu faço pro dnsmasq não limpar a cache quando a máquina reinicia?
E depois de ter feito isso, tem como eu determinar um tempo pra ela ser limpa?

Do FAQ do projto dnsmask:

Q: Can I get dnsmasq to save the contents of its cache to disk when
I shut my machine down and re-load when it starts again?

A: No, that facility is not provided. Very few names in the DNS have
their time-to-live set for longer than a few hours so most of the
cache entries would have expired after a shutdown. For longer-lived
names it's much cheaper to just reload them from the upstream
server. Note that dnsmasq is not shut down between PPP sessions so
go off-line and then on-line again will not lose the contents of
the cache.

Traduzindo: sem chance, ele não guarda em disco o cache para posterior utilizacao...
