systems checks the administrator can interact. You want it.

Handles restricted kernel modules. You need it as long as you are
using restricted kernel modules.

Load the modules listed in /etc/modules. Doesn't harm even if you
don't need it

Restore resolv.conf if the system crashed. Just runs once. You usually
want it if you are using ppp

You want it if you are running the rsync daemon (needs to be enabled
in /etc/default/rsync)

Most likely you want it if your hardware supports ACPI

rsync is disabled in /etc/default/rsync,  x11-common is only installed
if you have X and then you need it. You may want to disable
avahi-daemon if you don't need it.
