I wonder if this is the pppd daemon for point to point protocol (modems), I
would only start it if the installer detects a modem installed.

out! :) (I'm sure Alvaro[0] agrees here ;-)

legacy_run     17:22:09 lrc:/etc/rc3_d/S52imq

I would make an effort to port all this legacy_run services to SMF. Indiana
goal #654: No legacy in the main repositories! ;-)


online         17:20:35 svc:/network/nis/client:default


nis client out!

online         17:21:02 svc:/application/management/wbem:default


web manager out

online         17:21:02 svc:/network/ssh:default


I would leave ssh started by default. Okay, it's not common used, but it
saves your ass when your monitor doesn't works and you know the IP address.

online         17:21:53 svc:/network/smtp:sendmail


sendmail out, how many people needs a local smtp server enabled by default?
(maybe we can leave exim installed but disabled by default if people things
than an smtp service is really needed?)

online         17:22:06 svc:/milestone/multi-user:default


this one out too

 ...

I also think that every service related with hardware devices should be down
(for example, printing) if no printing is required.

Note that I'm not a solaris expert yet, and some of the removal sugestions
that I did can have consequenses on the main services that I'm not aware of.
So, please, Solaris gurus, be kind with me :)

What do you think should be turned off here?
