Where is FILE EDITION set so that autoconfig configures my env files properly?

I have been trying to find where FILE_EDITION variables are set.

if I run autoconfig on my fs1 file system things are pretty confused...

excerpt from VISR122_saturn.env on fs1:

##############################################

# Environment setting for Online Patching

##############################################

RUN_BASE="/R122/oracle/VISR122/fs1"

export RUN_BASE

PATCH_BASE="/R122/oracle/VISR122/fs1"

export PATCH_BASE

FILE_EDITION="run"

export FILE_EDITION

if test "$FILE_EDITION" = "patch"; then

   RUN_BASE="/R122/oracle/VISR122/fs1"

   export RUN_BASE

   PATCH_BASE="/R122/oracle/VISR122/fs1"

   export PATCH_BASE

......

But if I run it on my fs2 file system things look okay....
