release Fix FreeBSD: Swift Boot Times & Streamlined Efficiency

[Queen]

 

 

Hello everyone,

In this guide, I will share some practical tips for optimizing your FreeBSD setup, focusing on achieving faster boot times and improving the overall system experience through handy shortcuts.

1. Accelerated Boot Process:

To enhance your boot speed, first consider adjusting your boot time. By default, you typically wait for 10 seconds upon starting up. Here's how to modify that:

1. Edit Boot Configuration:
   Open /boot/loader.conf and add the following lines:

• This is the hidden content, please

  • Sign In
  • or
  • Sign Up

   

• Optimize Startup Scripts:
  You can update a few startup scripts to suppress unnecessary output during the boot sequence. Specifically, modify the following:

  • /etc/rc.d/ldconfig:
    Lines 40 and 60 can be changed to:

This is the hidden content, please

• Sign In
• or
• Sign Up

• /etc/rc.d/netif:
  Modify line 260:

This is the hidden content, please

• Sign In
• or
• Sign Up

• /etc/rc.d/routing:
  Update lines to:

• This is the hidden content, please

  • Sign In
  • or
  • Sign Up

   

• Optimize Randomness Checking:
  In /etc/rc.d/random, locate the random_start() function and comment out the following lines:

• This is the hidden content, please

  • Sign In
  • or
  • Sign Up

   

• Modify rc.conf:
  At the end of /etc/rc.conf, add the following lines:

• This is the hidden content, please

  • Sign In
  • or
  • Sign Up

   

• Clear Console on Login/Logout:
  Open both /etc/csh.login and /etc/csh.logout, and append the following line:

• This is the hidden content, please

  • Sign In
  • or
  • Sign Up

   

• Configure Getty Settings:
  In /etc/gettytab, locate the section starting with P|Pc|Pc console:\ and modify it as follows to clear the console after boot:

2. Creating Shortcut Aliases for Commands:

Aliases simplify command execution by creating shortcuts. This allows you to enter shorter, more memorable commands instead of the full paths or executions. The syntax is as follows:

• Sign In
• or
• Sign Up

For instance:

This is the hidden content, please

• Sign In
• or
• Sign Up

Functionality:

• This is the hidden content, please

  • Sign In
  • or
  • Sign Up

(Note: The -j5 option utilizes 4 CPU cores during compilation. Adjust this value based on your virtual machine's core count by adding 1. For example, if you have 8 cores, use -j9.)

While aliases remain in memory, they are lost upon reboot. To make them permanent, follow these steps:

3. Disabling the Sendmail Service:

Thanks to @martysama0134 for this tip: Preventing the Sendmail service from starting at boot can shave off another 10 seconds from your boot time.

1. Open /etc/rc.conf and either edit or add:

• This is the hidden content, please

  • Sign In
  • or
  • Sign Up

  (Note: In older FreeBSD versions, use "NONE" instead of "NO" for sendmail_enable.)

• Stop the Sendmail service immediately:

   • Sign In
   • or
   • Sign Up

    

That’s it! You’re now ready to reboot and see the improvements.

I hope you find these optimizations useful; they have certainly made a difference for me. Enjoy your day!
