[workaround] Unable to silence boot - efistub

jsaxx · 2023-05-30 21:47:17

I am trying to setup my efistub boot to be completely silent. I have managed to do so in the past following the instructions on Arch wiki (https://wiki.archlinux.org/title/silent_boot), yet on a new install I am unable to replicate.

Here is an example of the messages I am getting on boot:

This is how my efibootmgr setup looks like:

and this is my mkinitcpio configuration ("sudo mkinitcpio -p linux" has been run after swapping udev hook with systemd):

$ cat /etc/mkinitcpio.conf
# vim:set ft=sh
# MODULES
# The following modules are loaded before any boot hooks are
# run.  Advanced users may wish to specify all system modules
# in this array.  For instance:
#     MODULES=(usbhid xhci_hcd)
MODULES=(nvidia nvidia_modeset nvidia_uvm nvidia_drm)

# BINARIES
# This setting includes any additional binaries a given user may
# wish into the CPIO image.  This is run last, so it may be used to
# override the actual binaries included by a given hook
# BINARIES are dependency parsed, so you may safely ignore libraries
BINARIES=()

# FILES
# This setting is similar to BINARIES above, however, files are added
# as-is and are not parsed in any way.  This is useful for config files.
FILES=()

# HOOKS
# This is the most important setting in this file.  The HOOKS control the
# modules and scripts added to the image, and what happens at boot time.
# Order is important, and it is recommended that you do not change the
# order in which HOOKS are added.  Run 'mkinitcpio -H <hook name>' for
# help on a given hook.
# 'base' is _required_ unless you know precisely what you are doing.
# 'udev' is _required_ in order to automatically load modules
# 'filesystems' is _required_ unless you specify your fs modules in MODULES
# Examples:
##   This setup specifies all modules in the MODULES setting above.
##   No RAID, lvm2, or encrypted root is needed.
#    HOOKS=(base)
#
##   This setup will autodetect all modules for your system and should
##   work as a sane default
#    HOOKS=(base udev autodetect modconf block filesystems fsck)
#
##   This setup will generate a 'full' image which supports most systems.
##   No autodetection is done.
#    HOOKS=(base udev modconf block filesystems fsck)
#
##   This setup assembles a mdadm array with an encrypted root file system.
##   Note: See 'mkinitcpio -H mdadm_udev' for more information on RAID devices.
#    HOOKS=(base udev modconf keyboard keymap consolefont block mdadm_udev encrypt filesystems fsck)
#
##   This setup loads an lvm2 volume group.
#    HOOKS=(base udev modconf block lvm2 filesystems fsck)
#
##   NOTE: If you have /usr on a separate partition, you MUST include the
#    usr and fsck hooks.
HOOKS=(systemd autodetect modconf keyboard block filesystems fsck)

# COMPRESSION
# Use this to compress the initramfs image. By default, zstd compression
# is used. Use 'cat' to create an uncompressed image.
#COMPRESSION="zstd"
#COMPRESSION="gzip"
#COMPRESSION="bzip2"
#COMPRESSION="lzma"
#COMPRESSION="xz"
#COMPRESSION="lzop"
#COMPRESSION="lz4"

# COMPRESSION_OPTIONS
# Additional options for the compressor
#COMPRESSION_OPTIONS=()

# MODULES_DECOMPRESS
# Decompress kernel modules during initramfs creation.
# Enable to speedup boot process, disable to save RAM
# during early userspace. Switch (yes/no).
#MODULES_DECOMPRESS="yes"

According to the wiki
"""
Below are the parameters that you need to pass to your kernel to get a completely clean boot with systemd in your initramfs:

quiet loglevel=3 systemd.show_status=auto rd.udev.log_level=3

"""

Any idea of what I could be missing on?

well, you shouldn't see anything. you can try these workarounds:
https://wiki.archlinux.org/title/System … /dev/tty12
https://wiki.archlinux.org/title/Plymouth
note you won't see errors on boot at least with the first, you can show the logs with the second option when pressing [esc] during boot.

thanks for the pointers!

so killing plymouth using kernel params seems to achieve what I am looking for (https://wiki.archlinux.org/title/Plymou … parameters). I.e. black loading screen with no splash or msg. If anything goes south, I can always load into fallback where plymouth is enabled.

plymouth.enable=0 disablehooks=plymouth

Not sure if to mark this one as solved, as this is really more of a workaround and as far as I can see it should have been working with my original setup.

jl2 · 2023-05-31 12:21:29

from https://wiki.archlinux.org/title/Plymou … t_messages:

During boot you can switch to boot messages by pressing the Esc key.

so qou don't need the fallback kernel to see the messages.
I think you can mark it as solved (or as [workaround] )

Ah! Does that work even with Plymouth disabled?
Will be away for a while, so won't be able to check it. In any case marking this one as [workaround], it does what I want in the end

Thanks for the help!
