All packages in the archive function as expected.

A Malicious maintainer has installed a version of libc or whatever on his system that opens the way to a security hole. He builds a package on his system which links this libc statically and uploads it. Conclusion, there is a security hole in the uploaded packages that there is no way to trace given the sources only. Furthermore, it may even violate the GPL in some cases, where a maintainer uses a patch on his system, which is linked into a packages he uploads, and there is no trace of the source code for this patch anywhere. > I say that (b) is vastly superior to (a).

And you think than building the package in an environment corresponding to what _1_ maintainer use is better than building it in an environment that will be the same for every installed system once it is rebuilt.
