Arch/Grub - Disable booting message

Question

I just installed Arch Linux for the first time. I'd like to achieve just a black screen when booting until I'm asked for the login. I'm using grub as a boot loader. And added the line:

GRUB_CMDLINE_LINUX_DEFAULT="vga=current quiet loglevel=3 rd.udev.log-priority=3 splash

to the /etc/default/grub and updated grub, but I still see the message like

Booting >>Arch Linux<<

for a split second on startup (actually the text is german). I'm not 100% sure, whether this is printed by grub, but that's my current guess.

Does anybody have an idea how to troubleshoot this/hide the message?

Solution

In order to remove that message, go into /boot/grub/grub.cfg. Scroll down until you see the line ### BEGIN /etc/grub.d/10_linux ###. Right below, you'll see something like this:

menuentry 'Arch Linux' --class arch --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-simple-cdb0b113-f657-4b1b-a8e9-3fd0fb2c55d2' {
    load_video
    set gfxpayload=keep
    insmod gzio
    insmod part_gpt
    insmod fat
    set root='hd1,gpt1'
    if [ x$feature_platform_search_hint = xy ]; then
      search --no-floppy --fs-uuid --set=root --hint-bios=hd1,gpt1 --hint-efi=hd1,gpt1 --hint-baremetal=ahci1,gpt1  AAF7-73DC
    else
      search --no-floppy --fs-uuid --set=root AAF7-73DC
    fi
    echo    'Loading Linux linux-selinux ...'
    linux   /vmlinuz-linux-selinux root=UUID=cdb0b113-f657-4b1b-a8e9-3fd0fb2c55d2 rw cryptdevice=/dev/sdb3:root security=selinux selinux=1 init=/usr/bin/e4rat-lite-preload
    echo    'Loading initial ramdisk ...'
    initrd  /intel-ucode.img /initramfs-linux-selinux.img
}

Remove the lines that begin with echo and that boot message will be gone. Add quiet to your kernel parameters to disable boot messages in the kernel.

the answer given by @h313 does not actually achieve what was asked for. Note that the two echo statements begin with "Loading", and not with "Booting". That one is hard-coded into GRUB and in order to remove it, GRUB will need to be patched and recompiled. Alternatively, you may get lucky with github.com/ccontavalli/grub-shusher, which doesn't seem to be maintained, though.

This file starts with "DO NOT EDIT THIS FILE". Because it is auto-generated. Look in /etc/grub.d/ for the files from which it is generated, but I guess those belong to packages, and those may be overwritten as well.
