Barak Korren commented on OVIRT-899:
------------------------------------

The script as you wrote it above is more complex then it should be.
Try this:
{code}
while (> my.lock) 2> /dev/null; do
   sleep 5
done
{code}

> In order to make experimental flow atomic, we need to do as follows:
> in deploy.sh script and in start_testing_latest.sh we need to add a loop in the beginning of each script that does the following:
> *while 1:
> do
>   is_locked=$((echo aaa > my.lock) 2> /dev/null || echo is locked)
>   if [[ -z $is_locked ]]; then
>     break
>   else
>     sleep 5
>   fi
> done*
> Wrap the whole script with a  trap so in the end if each script we will be able to remove my.lock no matter what happened.
