The LEDs is the most convenient indicator of your ALIX. You need it to tell you at a glance that system is running or booted up OK.
As of 0.6.2, The LEDs are controlled in the /etc/init.d/voyage-util script.
During startup, the system will try to remount RO. If that fails, leds will not be set due to ”set -e” in script. To prevent this, edit /etc/init.d/voyage-util, move start_led to just after start:
...
case $1 in
'start')
start_leds
...
