Comment 3 for bug 1078183

I confirm this. The issue is in the init scripts for the agent, for the server and for the proxy. The issue has been fixed in the 2.0.3 version of the package (I did a comparison of the init scripts between 2.0.2 and 2.0.3).
Apparently there's a wrong evaluation in the _ev_ function on lines 28-30 . Here, this is the NON-working version from zabbix 2.0.2:

_ev_ () {
  [ "$VERBOSE" != "no" ] && eval $@
}

This is the working version from the package zabbix 2.0.3 (from Ubuntu Raring):

_ev_ () {
  [ "$VERBOSE" = "no" ] || eval $@
}

I copied the init scripts, recompiled the package and now it starts correctly.
