• Configures the kernel parameters via sysctl
• Runs the environment update script env-update.sh
• Removes stale lock files in /var/lock
• Removes stale files in /var/run
• Creates /var/run/utmp to allow login
• Resets pam_console permissions
• Creates a /var/lock.keep file to prevent portage from removing /var/lock
• Cleans up /tmp
• Creates some hidden X11 related directories in /tmp with root ownership
• Runs restorecon against the hidden X11 directories
• Creates the post boot dmesg log
