The i.admin Class
Action Script
# PKGINST parameter provided by installation service
# BASEDIR parameter provided by installation service
while read src dest
do
cp $src $dest || exit 2
done
# if this is the last time this script will be executed
# during the installation, do additional processing here.
if [ "$1" = ENDOFCLASS ]
then
# our config process will create a data file based on any changes
# made by installing files in this class; make sure the data file
# is in class `cfgdata' so special rules can apply to it during
# package removal.
installf -c cfgdata $PKGINST $BASEDIR/data/config.data f 444 root
sys || exit 2
$BASEDIR/bin/config > $BASEDIR/data/config.data || exit 2
installf -f -c cfgdata $PKGINST || exit 2

This illustrates a rare
instance in which installf is appropriate in a class action
script. Because a space file has been used to reserve
room on a specific file system, this new file may be safely added even though
it is not included in the pkgmap file.
The r.cfgdata Removal
Script
# the product manager for this package has suggested that
# the configuration data is so valuable that it should be
# backed up to $PKGSAV before it is removed!
while read path
do
# path names appear in reverse lexical order.
mv $path $PKGSAV || exit 2
rm -f $path || exit 2
done
exit 0
