How to disable the promt text line on the disk encryption screen

As suggested on Red Hat Bugzilla, a configuration file could be set for the deleting the text on the Plymouth/LUKS screen.

Here is a step-by-step summary to ask for confirmation of someone more experienced than me than the correctness of all the steps:

1. sudo touch /etc/plymouth/plymouth-populate-initrd.conf

2. sudo nano /etc/plymouth/plymouth-populate-initrd.conf

3. Insert the following content into the configuration file just created…

PLYMOUTH_DISABLE_LABEL_FREETYPE=1

4. Save the file (Ctrl+O) and close it (Ctrl+X)

5. Change the plymouth-populate-initrd script to let it read the new configuration variable…

   sudo nano /usr/libexec/plymouth/plymouth-populate-initrd

6. Add the code to read the configuration file at the beginning of the script, after the first lines of comment…

# Source configuration file if it exists
if [ -f "/etc/plymouth/plymouth-populate-initrd.conf" ]; then
    . /etc/plymouth/plymouth-populate-initrd.conf
fi

7. Find the corresponding code block and change the condition that includes label-freedype.so…

if [ -f "${PLYMOUTH_PLUGIN_PATH}/label-freetype.so" ] && [ "$PLYMOUTH_DISABLE_LABEL_FREETYPE" != "1" ]; then
     inst ${PLYMOUTH_PLUGIN_PATH}/label-freetype.so $INITRDDIR
     # The label-freetype plugin expects it at this location
     mkdir -p $INITRDDIR/usr/share/fonts
     [ ! -z "$DEFAULT_FONT" ] && ln -s "$DEFAULT_FONT" $INITRDDIR/usr/share/fonts/Plymouth.ttf
     [ ! -z "$DEFAULT_MONOSPACE_FONT" ] && ln -s "$DEFAULT_MONOSPACE_FONT" $INITRDDIR/usr/share/fonts/Plymouth-monospace.ttf
fi

8. Regenerate the initramfs…

   sudo dracut --force

9. Reboot
