Comment 5 for bug 1271188

Some suggestions (possibly combine them based on what is possible):

1) Log the download and extraction somewhere and point people at that log.

2) Print the total number expected in the GUI in that message.

3) Estimate the total size somewhere so we know how long to wait.

4) Import images as they come in instead of all at the end. This can show things are progressing and not stuck on network access.

5) print location that bootimages are being downloaded to, savy admins who are impatient can use du and find to satisfy their curiosity.
