ifeq (yes,$(shell dpkg-vendor --derives-from Ubuntu && echo yes)) DEFAULT_CMDLINE := quiet splash DEFAULT_TIMEOUT := 10 DEFAULT_HIDDEN_TIMEOUT := 0 followed by ifneq (,$(DEFAULT_HIDDEN_TIMEOUT)) perl -pi -e 's/^GRUB_TIMEOUT=.*/GRUB_HIDDEN_TIMEOUT=0\nGRUB_HIDDEN_TIMEOUT_QUIET=true\n$$&/' \ debian/grub2-common/usr/share/grub/default/grub at about line 367. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1258597 Title: Warning: Setting GRUB_TIMEOUT to a non-zero value when GRUB_HIDDEN_TIMEOUT is set is no longer supported.
