Debian Rc.local Equivalent

In many distributions you can add commands to run certain programs at the end of the boot process after all system services have been started into the /etc/rc.d/rc.local file, however there is no such file in a Debian system. Here is the way to accomplish the same thing the debian way:

Make a file called /etc/init.d/local with a text editor. This file is a script so it should always start with the following line:

#! /bin/sh

Next, for example I have an always on cable modem and I want to use rdate to update the system time to atomic clock time at startup, so I add the following command to the file:
```
rdate -s clock-1.cs.cmu.edu && hwclock --systohc
```

(The rdate command updates your system time, then the hwclock command updates the bios clock)

Make this file executable with:
```
chmod +x /etc/init.d/local
```
Next, link the new local file by running:
```
update-rc.d local defaults 80
```

Debian Rc.local Equivalent

No, it is not rc.local equivalent:

% update-rc.d local defaults 80
 Adding system startup for /etc/init.d/local ...
   /etc/rc0.d/K80local -> ../init.d/local
   /etc/rc1.d/K80local -> ../init.d/local
   /etc/rc6.d/K80local -> ../init.d/local
   /etc/rc2.d/S80local -> ../init.d/local
   /etc/rc3.d/S80local -> ../init.d/local
   /etc/rc4.d/S80local -> ../init.d/local
   /etc/rc5.d/S80local -> ../init.d/local

It is also called when shutting down.

The right way is:

% update-rc.d local start 80 2 3 4 5 .
 Adding system startup for /etc/init.d/local ...
   /etc/rc2.d/S80local -> ../init.d/local
   /etc/rc3.d/S80local -> ../init.d/local
   /etc/rc4.d/S80local -> ../init.d/local
   /etc/rc5.d/S80local -> ../init.d/local
