I build the SDK in such a way that the users do not need to run relocate-sdk.sh if they unpack to /opt/mysdk. > The problem is with step 2: currently it requires the build process to move the SDK to /opt/mysdk, then run relocate-sdk.sh, before > producing the final tarball. > This is often problematic because on the SDK maintainer's machine, `/opt/mysdk` usually already exists and contains the latest > stable release. > With this new argument, the build process can be simplified for the SDK maintainer. The problem with that, is that users are not free to have the SDK where they want. That would prevents them from having multiple versions of the SDK installed at once (e.g. when they have to work on a maintenance branch to fix bugs in an older releae for example), without removing an SDK before they install a new one. And as a consequence, that also prevents the person responsible for the SDK, to work on older SDK to pinpoint issues without removing the "latest" SDK first... I don't think this is a good way to use the SDK... I think the relocation step should really be run by the person extracting and using the SDK, on their machine. I'm still leaving this patch pending, because I still feel the burn from last time, so if another maintainer is interested in this, they will have to apply it (and expand the commit log to carry the explanations you provided in this reply, thanks!).
