Honestly, regarding the server side of live, it doesn't make a
difference. 2.5 - 4 minutes hardware init time and then having an OS
which boots up in less then 10 secs

I'm more concerned about the non-transformed startup scripts which are
still sysv.

e.g. Tomcat6.

------------------------- snip ---------------------
The default file could look like this:
# Run Tomcat as this user ID. Not setting this or leaving it blank will
use the
# default of tomcat6.
TOMCAT6_USER=tomcat6

# The home directory of the Java development kit (JDK). You need at
least
# JDK version 1.5. If JAVA_HOME is not set, some common directories for 
# OpenJDK, the Sun JDK, and various J2SE 1.5 versions are tried.
JAVA_HOME=/usr/lib/jvm/java-6-sun

# Directory for per-instance configuration files and webapps. It
contains the
# directories conf, logs, webapps, work and temp. See RUNNING.txt for
details.
# Default: /var/lib/tomcat6
#CATALINA_BASE=/var/lib/tomcat6

# Arguments to pass to the Java virtual machine (JVM).
JAVA_OPTS="-Djava.awt.headless=true"
JAVA_OPTS="$JAVA_OPTS -Xmx4096M"
JAVA_OPTS="$JAVA_OPTS -XX:PermSize=256M"
JAVA_OPTS="$JAVA_OPTS -XX:MaxPermSize=512M"
JAVA_OPTS="$JAVA_OPTS -XX:+UseConcMarkSweepGC"
JAVA_OPTS="$JAVA_OPTS -Dcom.sun.management.jmxremote.port=9003"
JAVA_OPTS="$JAVA_OPTS
-Dcom.sun.management.jmxremote.password.file=/etc/tomcat6/jmxremote.password"
JAVA_OPTS="$JAVA_OPTS
-Dcom.sun.management.jmxremote.access.file=/etc/tomcat6/jmxremote.access"
JAVA_OPTS="$JAVA_OPTS -Dcom.sun.management.jmxremote.ssl=false"
JAVA_OPTS="$JAVA_OPTS -Djava.rmi.server.hostname=xxx.xxx.xxx.xxx"

# Java compiler to use for translating JavaServer Pages (JSPs). You can
use all
# compilers that are accepted by Ant's build.compiler property.
#JSP_COMPILER=jikes

# Use the Java security manager? (yes/no, default: yes)
# WARNING: Do not disable the security manager unless you understand
# the consequences!
#TOMCAT6_SECURITY=yes
TOMCAT6_SECURITY=no

# Number of days to keep logfiles in /var/log/tomcat6. Default is 14
days.
#LOGFILE_DAYS=14

--------------------------------------------------

Those configs need to be handled carefully, when we move from sysV to
upstart job files.
