I think that many can learn from this.
Instead of defaulting with everything enabled, default with the
services installed but disabled so they can be easily enabled. This
is fairly easy to do and something that has gradually changed in the
free UNIX(r) community over the past years.
RedHat (for example) no longer enables every possible service
by default and requires you to enable these features to protect your
machine from being compromised by software you didn't know you had.
Not every machine needs to run its own nameserver.
While there are some services that are safe(er) to have enabled
by default as it improves the usability of the machine, some of
these things are just silly to be enabled on consumer (home) machines.
I hope all the vendors out there get a clue on this and stop
enabling insecure methods of access by default. (eg: telnet)
