Additionally to updating gnulib, often some projects need to sync additional
files from the freshly updated gnulib subdirectory, like e.g. bootstrap or 
COPYING.

In December, I've suggested [1] the new makefile target 'update-gnulib-to-lates'
(alias 'gnulib-sync') which allows to specify a hook to perform such additional
tasks - see attached.

In coreutils, the hook for copying the extra files boils down to (in cfg.mk):

+# Override gnulib to copy some files from there during 'make gnulib-sync'.
+cu_GNULIB_SYNC_HOOK:
+       @{ cd $(srcdir) \
+           && set -x \
+           && cp gnulib/doc/COPYINGv3 COPYING \
+           && cp gnulib/build-aux/bootstrap bootstrap \
+           && cp gnulib/tests/init.sh tests/init.sh \
+       ; }
+export _gl_GNULIB_SYNC_HOOK = cu_GNULIB_SYNC_HOOK

WDYT?

Have a nice day,
