The cheat sheets are useful for reference, but I'd strongly encourage |
| 12 |
anybody using systemd to get a decent understanding of the |
| 13 |
fundamentals. |

I gave a presentation along these lines which can be found at: |

Some key concepts you should understand: |
| 21 |
1. Targets as "virtuals" - if you think about them the way you'd |
| 22 |
think about a virtual package you'll probably grok it. |
| 23 |
2. Before/After/Wants/Requires and what they actually mean |
| 24 |
3. Drop-ins |
| 25 |
4. Creating dependencies using /etc/systemd/system/foo.xxx.d |
| 26 |
symlinks, and how these tie into enabling services |
| 27 |
|
| 28 |
Just as with openrc there are a lot of building blocks which are used |
| 29 |
to create a working configuration, there are many ways to do the same |
| 30 |
thing, and some of those ways are usually better than others. The |
| 31 |
overall design is somewhat different, so you need to look at things |
| 32 |
differently to make the most of it. |
