I just meant that if you want to validate the downloaded file then you
should get the checksum from a different mirror. If the file is
compromised on one server then the checksum file migt be too. In that
case there would be no detectable error. With tho servers there would
be warnings if either the leap second file or the checksum file was

Anyway, I did not make enough research. Now I have found a place to
download the file, but there is not any obvious checksum file. Perhaps
you really have to download the entire file more than once to make
sure. Looks like most of my points are moot.
