Hi, thank for you the patch. But I think it is better to just update the
file from Gnulib. The version used by Grub is old and missing many
improvements/fixes:
$ grep '^scriptversion=' bootstrap
scriptversion=2022-01-26.05; # UTC
Here is the updated version:
$ cp $GNULIB_SRCDIR/build-aux/bootstrap .
$ grep '^scriptversion=' bootstrap
scriptversion=2025-06-10.02; # UTC
The issue this patch addresses is fixed in Gnulib with this commit:
commit e319c0feea5088fe7774f44919756a54e963d1ac

bootstrap: Fix recognition of --depth option with recent git releases.
Reported by Benno Schulenberg <bensb...@telfort.nl> in
<https://lists.gnu.org/archive/html/bug-gnulib/2025-02/msg00106.html>.
* top/bootstrap-funclib.sh (prepare_GNULIB_SRCDIR): Assume that
'git clone' and 'git fetch' support the --depth option.
* build-aux/bootstrap: Regenerated.
Thanks,
Collin
