Now, that's a good question. The answer is more along the lines of
knowing what is in your system, and so what options you can check off.
For example, if you know you have no SCSI cards, uncheck all of them;
it will make the compile go much faster. Ditto for things like
firewire support, or that odd I2C stuff. Also you could uncheck all
the other disk and network controllers, etc, that you don't have and
won't ever have.

You do take the risk that if you add such a device in future, you will
need to re-compile to get it to work. But hey, everything's a
trade-off. :-)

Fraid I don't know of any for Linux. If it were Windows, I'd say Black
Viper's site.
<http://www.blackviper.com/>

He lists most of the popular services running under Windows, and when
and why you could turn them off. It does result in lower memory usage,
I know that. But I don't recall seeing a similar optimizing site for
Linux services. Oh, there are some you can easily figure out - turn
off telnet if you don't use it, and instead use only SSH, etc.
