3 Software Configuration
3.3. Activating and Deactivating Services
Some services will be started as daemons at system startup and hence reduce the amount of free
memory and increase the boot time. You can use one of the following options to deactivate the
unused services at startup or start them only on demand:
• rename links under /etc/rc2.d
10
(see Table 3).
• use sysv-rc-conf
11
as graphical console program for the first method
• start the service over inetd
12
• start manually via /etc/init.d

3.4. udev
Since kernel 2.6.26.5 Complete Image uses udev
13
to create devices in /dev directory. The network
interfaces are not bound to their MACs in order to be able to use only one system image on various
devices
14
. To change this behavior in Debian 4.0 Etch uncomment following line in
/etc/udev/rules.d/z45_persistent-net-generator.rules:
#KERNEL=="eth*|ath*|wlan*|ra*|sta*", DRIVERS=="?*",\
# IMPORT{program}="write_net_rules $attr{address}"
To change this behavior in Debian 5.0 Lenny change following line in
/etc/udev/rules.d/75-persistent-net-generator.rules:
KERNEL!="eth*|ath*|wlan*[0-9]|msh*|ra*|sta*|ctc*|lcs*|hsi*",
\ GOTO="persistent_net_generator_end”
to
KERNEL!="ath*|msh*|ra*|sta*|ctc*|lcs*|hsi*",
\ GOTO="persistent_net_generator_end"
/etc/udev/rules.d/custom.rules has rules to create symlinks to I2C and RTC devices:

All relevant settings were removed from /etc/udev/rules.d/z25_persistent-net.rules for Debain 4.0 Etch and
from /etc/udev/rules.d/70-persistent-net.rules for Debian 5.0 Lenny
