Boot sequence (rc.)
A small reminder regarding the Run Levels in Debian.
| Level | Purpose | Managed by |
|---|---|---|
| 0 | Halt sequence | both (OS + user) |
| 1 | Single-user mode (for special administration) | OS |
| 2 | Local Multiuser
also know as "Basic Multiuser" Local network (loopback 127.0.0.1) is up & all interfaces are registered. .. But there is NO NETWORK access and services (no NFS, Samba, etc.) |
user |
| 3 | Full Multiuser with networking text mode | OS |
| 4 | Full Multiuser with networking text mode | user |
| 5 | Full Multiuser with networking graphical mode | both (OS + user) |
| 6 | Reboot |
Then each script as both an execution state and a priority.
- S => Start script
- K => Kill script
Scripts are executed in order: from the lower to the highest number = from 00 to 99.
