Hello. I'm still a relatively new Debian maintainer, and learning the ropes. I have a package (oo2c, an optimizing Oberon-2 compiler) which is presently released for i386. A bug-report was filed against it, that it did not build on Alpha, and I therefore investigated the matter with the upstream maintainer. He advised that there was a separate 64-bit version which was largely untested, and we have therefore begun work attempting to shake out the bugs, and potentially reach a point where the code will work on other platforms.
Assuming that I can manage to create a working Alpha executable, nevertheless I am not sure how then to go about releasing a multi-platform package? Does there have to be a separate Alpha maintainer, Sparc maintainer, etc.? Even though I can compile and test via remote shell, I do not have a local Alpha system and would not upload my private PGP key to a remote server for package signing. Can I create an unsigned package, download that to my local server and then sign it? Is there another recommended procedure?
