# ports vs base
|
||||
- Base-System ist vollständiges Betriebssystem (nicht nur Kernel)
|
||||
- Hackbar: ein Source-Tree, ein Build-System ([`man release`](https://man.openbsd.org/release))
|
||||
- `release` / `-current` / `-stable`
|
||||
- `sysupgrade` / `syspatch`

# Startup
|

- Kernel startet `init`
|

- `init` führt `/etc/rc` aus (ein Shell-Script)
