I've seen it provided by both ISC and official (in this case, SGI) vendors, so
I think it's a good bet that a syslog server name can be provided during lease
acquisition.

However, it is entirely possible and indeed workable, I think, to simply send
the raw syslog message using sockets and avoid a syslog API altogether,
leaving the remote log server to make sense of it (which has already been
mentioned by someone else, and is I think the default behaviour of syslog -
but I'm wiling to be corrected). But smarter heads than mine will decide.
