I'm on my way to cleanup my system , started from init scripts , and found:

/etc/rcS.d/S25brltty

The description header wasn't helpful enough, and what's that used for, and if it's safe to purge ?

The links in /etc/rc?.d/ point to scripts in /etc/init.d/. As for brltty, it sounds like an accesibility feature for some Braille thing.

First, try to find out to which package it belongs:

$ dpkg -S /etc/init.d/brltty 
brltty: /etc/init.d/brltty

Well, that's clear, the brltty package is responsible for this. Let's get more information about it:

Excerpt from apt-cache show brltty:

Description-en: Access software for a blind person using a braille display
 BRLTTY is a daemon which provides access to the console (text mode)
 for a blind person using a braille display.  It drives the braille
 display and provides complete screen review functionality.

You can safely remove it, nothing really depends on it if you do not have a braille display (checked with apt-cache rdepends brltty)

apt-cache show is nice ! –  warl0ck Dec 10 '11 at 10:57

Brltty enables braille accessibility for people with impaired vision. So yes, it's safe to remove if you're not blind or wear glasses!

sudo apt-get remove --purge brltty

If you don't need printing support you can also safely remove and purge cups-daemon.

sudo apt-get remove --purge cups-daemon

To discover some more services and easily enable or disable them I installed bum (BootUp-Manager), a graphical tool for non-geeks.

sudo apt-get install bum
