The journal works without permanent storage (one more of its many |
| 19 |
advantages); in that case, it keeps a small amount of logs in memory (you |
| 20 |
can set how much memory to reserve for it). |

Only if you want to have logs in permanent storage. In that case, you only |
| 25 |
need to create the /var/log/journal dir with systemd-journal GID, and 2755 |
| 26 |
permissions (with setgid). systemd-journald will automatically rotate the |
| 27 |
logs when they use 10% of the free disk available (you can also change |
| 28 |
that). |
| 29 |
|
| 30 |
Since the logs are compressed and indexed, each entry on them is accesible |
| 31 |
in O(1), and they don't use that much space (with 280 megabytes reserved in |
| 32 |
my laptop for journal logs, I have logs since Sep 20, 2014; that's 5 months |
| 33 |
worth of logs, although my laptop doesn't run that many daemons). |
| 34 |
|
| 35 |
Anyway, the journal works perfectly without permanent storage (as you can |
| 36 |
see); if you are happy that way, you don't need to enable it. |
