[PATCH] configure: replace --enable/disable-git-update with --with-git-submodules
Posted by Dan Streetman 3 years, 6 months ago 
Replace the --enable-git-update and --disable-git-update configure params
with the param --with-git-submodules=(update|validate|ignore) to
allow 3 options for building from a git repo.

This is needed because downstream packagers, e.g. Debian, Ubuntu, etc,
also keep the source code in git, but do not want to enable the
'git_update' mode; with the current code, that's not possible even
if the downstream package specifies --disable-git-update.

Re: [PATCH] configure: replace --enable/disable-git-update with --with-git-submodules
Posted by Dan Streetman 3 years, 4 months ago 
Hi, just a ping to try to keep this alive, does the patch look ok? I
can rebase it on the latest git if so (and if needed)
