I'm pretty new to Linux and I would be interested in finding ways to reduce the boot time, specially in embedded-related environments.



I've read somewhere of a method to avoid the kernel to load some drivers or modules but I'm completely lost and all the information I find on internet is quite complex and dense.



Could anyone please suggest any book, document, website or point me in the right direction on the general steps needed to achieve this? Maybe I'm wrong and this is nothing to do with the Kernel.



Thanks and sorry for my ignorance!

          The arch linux documentation Improving performance/Boot process may help you to learn how to improve the boot performance.



          Use systemd-analyze blame to check the timing for the enabled services, or systemd-analyze critical-chain to check the critical points then disable the unwanted services through systemctl disable service_name. or removing the un-necessary programs through apt.

          One-line joke

          A one-liner is a joke that is delivered in a single line. A good one-liner is said to be pithy - concise and meaningful. [1] Comedians and actors use this comedic method as part of their act, e.g. Jimmy Carr, Tommy Cooper, Rodney Dangerfield, Norm Macdonald, Ken Dodd, Stewart Francis, Zach Galifianakis, Mitch Hedberg, Anthony Jeselnik, Milton Jones, Shappi Khorsandi, Jay London, Mark Linn-Baker, Demetri Martin, Groucho Marx, Dan Mintz, Emo Philips, Tim Vine, Steven Wright and Henny Youngman and Arnold Schwarzenegger. [ citation needed ] Many fictional characters are also known to deliver one-liners, including James Bond, who usually includes pithy and laconic quips after disposing of a villain. [ citation needed ] Examples "A baby seal walks into a club." "A dyslexic man walks into a bra." (Anonymous) "There are three types of people, those who can count and those who can't." "Venison's dear, isn't it?" (Jimmy Carr) "An escala...
