Message-ID: <8916.1245303178@jrobl> (raw)


After the failure of open(2) with ETXTBSY, IMA produces wrong messages.
Here is a simple test script.

dir=/tmp
cp /bin/sleep $dir
ls -l $dir/sleep
stat -f $dir
$dir/sleep 3 & sleep 1
echo | /bin/dd of=$dir/sleep conv=notrunc && false
wait
rm $dir/sleep


The result.
