[ptxdist] Do ipkg-push with SHA256 checksums

[Simon Falsig <sfalsig@verity.ch>]

Hi,

I'm trying to setup ipkg-push to repository, generating a signed Packages list with SHA256 checksums (using opkg, and the --checksum SHA256 parameter). From what I can see though, the ipkg-push is done by scripts/ipkg-push, which doesn't have a way of setting the checksum type, and just calls ${TYPE}-make-index without any parameters. I can easily hack something together to make this work for me (by just modifying the ipkg-push script), but is there a more correct way?

Judging from the ipkg-push file, it's made to support not just opkg, but also ipkg, which I don't think supports the SHA256 checksum. So just blindly adding the checksum parameter to the commandline would not maintain the generic support. On the other hand, I haven't found any other users of the script than ones where it's called with opkg as the type.

Suggestions:
- Make ipkg-push just support opkg, and allow the checksumtype to be specified as a parameter to the script (image_ipkg.make already generates the local using opkg-make-index only)
- Maintain ipkg/opkg support by making some more elaborate parameters (for instance an "make-index-extra" that is then just passed from ipkg-push to ${TYPE}-make-index
- Pull index generation out of ipkg-push, and let it be done by image_ipkg.make instead (which seems to be the only other place that is currently calling any of the -make-index functions)
- Something entirely different

Any input is welcome! Thanks in advance!
