Description Xianghua Chen 2017-03-08 01:34:51 UTC
Description of problem:
Typo error in virt-dib man page:
manual page  | wrong word                                    | correct word
virt-dib     | The supported checksums are MD5, and SHA256.  |  The supported checksums are MD5, and SHA512. 

The word "SHA256" should be replaced with "SHA512" in this sentence because it actually output the sha512 checksum file.  
It's under the --checksum part.

Comment 1 Pino Toscano 2017-03-08 08:57:32 UTC
Actually, the documentation is correct, but I made a typo in the list of checksums to generate: diskimage-builder generates SHA256 (in addition to MD5), so that is what virt-dib should generate as well as result of --checksum.

Fixed upstream with

Comment 3 Xianghua Chen 2017-03-09 02:48:59 UTC
Verified with package:

1. Build fedora22 with --checksum:
# virt-dib -B /usr/share/diskimage-builder/lib -p /usr/share/diskimage-builder/elements --envvar DIB_RELEASE=22 --name fedora22  fedora vm --checksum
2. Check the sha256 file has been generated successfully:
# ls
fedora22.d  fedora22.qcow2  fedora22.qcow2.md5  fedora22.qcow2.sha256
# cat fedora22.qcow2.sha256
6fc4ce325dddbaa8de0fa08a2b603d3be70910e0d5d7c9b8c0050fc1b6213993  fedora22.qcow2

So verified.
