When the serial or telnet port is not in use, a single D3 turnkey respawn can be disabled. Comment out the inittab entry with the # sign, as in:
|
#a1:2:respawn:d3 -n pick0 1 -t tty2 |
Another way to do this is to delete the entry in question, or replace the process information for a tty with a valid /etc/getty command sequence, rather than d3.
Execute the command init q to activate any changes to the inittab file.

WARNING |
The file /etc/inittab is a highly sensitive UNIX system configuration script. Any changes made to this file must be accurate. Invalid entries can cause unpredictable events to occur in UNIX, including system hangs and rapidly respawning processes. |
