Sorry, I found this piece of --help contradict the last sentence I wrote: If you maintain a package and want to pin a particular revision of the Gnulib sources that has been tested with your package, then there are two possible approaches: either configure a 'gnulib' submodule with the appropriate revision, or set GNULIB_REVISION (and if necessary GNULIB_URL) in bootstrap.conf. So it seems having a git submodule for gnulib and using GNULIB_REVISION at the same time is not supported. FWIW, I'm going to experiment in libntlm and use GNULIB_REVISION in bootstrap.conf instead of a git submodule, to allow a downloaded tarball of git HEAD to be a supported way of building the package from source. This hasn't worked historically for reasons discussed in this thread, but given the xz backdoor I think there is value in supporting this approach. /Simon
