Hi dear GNU wget developers (Tim et al.), The 'bootstrap' script from Gnulib has been reorganized to work in two phases: (1) Fetch auxiliary files that are not in the git checkout. This is the part that requires network access and that has supply-chain concerns. (2) Generate files such as configure, config.h, Makefile.in etc. This includes running gnulib-tool.
See <https://lists.gnu.org/archive/html/bug-gnulib/2022-07/msg00053.html> for details. For GNU wget2 some adjustment of the bootstrap.conf is needed: The clone_wiki invocation, which makes network accesses, needs to be moved from the bootstrap_post_import_hook to the bootstrap_post_pull_hook. This adjustment will be needed the next time you use the '--bootstrap-sync' option. Bruno
