SUMMARY: How to set Solaris 10 tcp tuning parameters to last thru reboot?

I asked how, in Solaris 10, to make the following parameters persist thru
reboots - putting them in /etc/system no longer seems to work:

set tcp:tcp_conn_req_max_q0=4096
set tcp:tcp_conn_req_max_q=1024

Thanks to all for the quick responses.

* A number of people suggested creating an /etc/rc2.d/S* (or possibly
rc3.d) script with the ndd commands, as in:
       ndd -set /dev/tcp tcp_conn_req_max_q0 4096
       ndd -set /dev/tcp tcp_conn_req_max_q 1024

  and one respondent pointed me to this related reference
                                "As per CISecurity tcp stack hardening

* I received a pointer to this possible solution: 
but I don't see anywhere in the referenced script it that seems to invite
user settings, so I decided against it.
