What we have is:
* external signed checksums using 4 different algorithms, to allow
for download verification
* an internal md5sums.txt file that can be used after boot to check
the integrity of the individual files inside the installation media
(to check for issues with writing to optical media, bascially)
* checksums of all the installable packages, in the Packages files
etc.
