There are a few problems with download_prerequisites are described in PR 82704. The first is on busy-box version of shasum and md5sum the extended option --check don't exist so just use -c. The second issue is the code for which shasum program to use is included twice and is different. So move which program to use for the checksum after argument parsing. The last issue is --md5 option has been broken for sometime now as the program is named md5sum and not just md5. Nobody updated switch table to be correct. contrib/ChangeLog: PR other/82704 * download_prerequisites: Fix issues with --md5 and --sha512 options.

|
--no-graphite same as --no-isl
|
|
--verify verify package integrity after download (default)
|
|
--no-verify don't verify package integrity
|
|
--sha512 use SHA512 checksum to verify package integrity (default)
