Resume download if connection suddenly terminated and doesn't match with checksum #100
Description
When downloading squash/initrd from github at slow connection (this including from the docker web). Sometimes github server terminate the connection suddenly at specific minutes. Consider to do a checksum to the downloaded images, and if it doesn't match resume the download so the image become fully matched.
I have several /dev/loop mounting error when i try to boot the live cd through PXE. While i finally realized the downloaded squashfs is not fully at its original size.
