No, you're wrong. nscd only caches passwd, group, hosts data. Nothing
And I'm reluctant to add support for rarely used other services because
the cost doesn't really justify the gains. For this problem, as I told
Phil already internally, I think it's perfectly fine to use nss_db.
It's really static data so updating the database when a) the
/etc/services file changes or b) the nss_db implementation changes, is
no big issue.
