This is an example of a failed download using imgadm import. To my mind,
imgadm should simply exit when it decides to abort the download and
avoid needlessly ploughing on with checksums which are obviously going
to fail.

Granted, this is a result of my sometimes less than stellar broadband
connection, but imgadm should really deal with this in a cleaner fashion
(IMHO).
A "nice to have" feature here would be the ability to continue a failed
download.
Alternatively, is there a means of deriving the URL(s) for the
components of a given image and downloading manually, e.g. via 'curl -C'
to handle download failures?
