> What I also don’t get: why the hell would do I care which NTP implementation is used in most cases. Because some implementations have time jump while others have it slew it slowly. On boot-up a jump may be fine to get with ± some number of milliseconds, but once the system is running, there are situations where jumps could be a problem (especially in the negative direction, where a moment is "repeated"). > But honestly as long as when I boot my Debian-derived distro it works as expected why am I going yo go digging into how it works? What can I possibly gain by switching which DHCP client or which NTP daemon I’m using? Because as a sysadmin it is your job to understand how a system works. There should be very little "magic" happening. Sure there are many times where things Just Working™ is fine (it's why I run a Mac at home), but many others where you should understand why things are working the way they are.

> Because as a sysadmin it is your job to understand how a system works. No, as a sysadmin your job is to deliver a working system. To do that it usually helps to understand how the system works, but it's not a necessity. As long as something keeps working, and you're equipped to go digging if and when it's necessary, it's fine to not understand or know how something works.

  you can ride and breed horses without understanding horse physiology or DNA. when you need to fix a broken or lame horse or breed a better horse, knowing how it works helps alot presumably most sys admins are more akin to vets than riders

I am a sysadmin for some systems. I am merely a user for others. Servers that run my projects? Sure I will dig into what’s up. My Raspberry Pi running Raspbian so I can run my 3D printer off it? I’m a user.
