Boot Penguins

The Linux kernel is designed to display penguins when booting. One penguin per CPU core. Some distros come with this feature enabled and some do not.

To enable the display requires compiling the kernel with the CONFIG_LOGO=y option.

If that option is set and the penguins are not desired then the penguins can be disabled with the boot parameter logo.nologo.

Commonly a copy of the kernel configuration is installed at /boot/config. If not, the configuration is available at /proc/config.gz. To learn whether the logo configuration is enabled:

zgrep ^CONFIG_LOGO= /proc/config.gz

If there is no result then the option is not enabled.
