Read only the last three messages of the thread, hoping to not say
idiotic things.
Rewriting the previous script in the following manner:

[code]
VARS_TO_EXPORT="BOOT CONSOLETYPE CRITICAL_SERVICES START_CRITICAL
STOP_CRITICAL OLDSOFTLEVEL SOFTLEVEL IN_BACKGROUND IN_HOTPLUG"

RUNSCRIPT="/bin/env -i"
for i in ${VARS_TO_EXPORT} ; do
    RUNSCRIPT="${RUNSCRIPT} ${i}=\${${i}}"
done
RUNSCRIPT="${RUNSCRIPT} /lib/rcscripts/sh/runscript.sh $*"
eval $RUNSCRIPT
[/code]

should make it easyer to maintain, also "VARS_TO_EXPORT" could be placed
in /etc/rc.conf (with a better name) .
Running the rc scripts from a clean environment make easyer to debug
things, it caused at least one headheache to me installing SuSE + apache
+ php + informix some years ago.

just my 2 cents.
