# What Is SystemD

In this 👉 [video](https://tilvids.com/videos/watch/efa16927-168c-4d38-af61-cbd29c1716cd) Nick from [TheLinuxExperiment](thelinuxexperiment_channel@tilvids.com) goes over SystemD

Video breakdown..

(Watch the video for a really good explanation of SystemD)

### What Are Init Systems?

- Initialization service

- 1st thing to start up

- launches services in proper order

### Is SystemD Bloated?

- Does non-init things

- Keeps getting bigger over time

- Still modular, so it can be small

- Bloat depends on implementation

- Many distros implement a lot, so systemd is big

- Hard to argue it's not bloated

### Does Everything Depend On It?

- SystemD is so pervasive things can't function w/out it

- Other solutions = more work

### Red Hat Project?

- Red Hat started it, but many work on it

- 1 company w/control = bad

- It can be forked

### Restricts Choice/Modularity?

- Other choices do exist

- With do many distros using systemd, it's hard to not to use it development

### Makes Linux Less Secure?

- Usage on so many distros = bigger target

- Big projects may be less secure

- SystemD is better maintained than a bunch of smaller projects would likely be maintained

### Why Use SystemD

- Unified project = learn 1 system to manage many things

- Processes can start in mostly any order

- Well integrated into Linux Kernel

- Written in C, faster than script init systems

### Conclusion:

- Use whichever init system comes w/distro
