oops, I missed sending Kernel John the previous message directly
here is an findaufs.sh script that seems to be a good start for my aufs
implementation
#!/bin/bash
echo Usage: $0 "'*filename*' '*path*'"
FINDTXT=$1
PATHTXT=$2
AUFS=aufs
AUFSTMP=/tmp/$AUFSmnt.tmp
cat /proc/mounts | grep $AUFS > $AUFSTMP
CTR=2
while [ $CTR -lt 256 ]; do
LN=`cat $AUFSTMP | cut -d : -f $CTR | cut -d = -f 1`
if [ "$LN" != "" ]; then
if [ "$PATHTXT" == "" ]; then
find $LN/ -name $FINDTXT
else
find $LN/ -name $FINDTXT | grep $PATHTXT
fi
fi
let CTR+=1
done
