In OpenBSD, you can set the default boot time by modifying the /etc/boot.conf file. The /etc/boot.conf file specifies the options that are used when the system is booted.
To set the default boot time in OpenBSD, follow these steps:
Open the /etc/boot.conf file: Open the /etc/boot.conf file in a text editor.
Set the timeout option: The timeout option specifies the number of seconds that the boot menu is displayed before the default entry is automatically selected. To set the timeout, add the following line to the /etc/boot.conf file:
timeout seconds
Replace seconds with the number of seconds that you want the boot menu to be displayed before the default entry is selected. For example, to set the timeout to 5 seconds, you would enter the following line in the /etc/boot.conf file:
timeout 5
Save the file: Save the changes to the /etc/boot.conf file.
Reboot the system: To apply the changes, you will need to reboot the system. You can do this by running the reboot command:
reboot
This will reboot the system and apply the changes to the boot menu timeout.
Keep in mind that these are just general steps, and your specific configuration may vary depending on your system's setup. Consult the OpenBSD documentation for more detailed information.
