Studio2 Suicide After Reboot

If you have to reboot the Studio2 appliance it will lose its OS image ISO internal loopback mounts. Upon losing them it will not simply try to remount them, instead it will try to download the image again but will save it with an indexed extension over and over until your Studio2 disk is full.

There are two fixes involved. The first simply attempts to remount the ISO. The second deletes the ISO (fragment?) before attempting to redownload the same image.

Here's the patch:

I also stripped out the retry and timeout arguments to wget as they were causing wget to abort on a peer reset instead of continuing with a new connection.

If you've run into this problem do delete all the files in the download ISO cache:

rm -vf /opt/vmware/cache/build/ISO/*
