Create a build directory that will also be your frugal install directory. Open a terminal in it's path.	

The commands are indented and comments and instructions start at the left margin.

Create a rootfs folder
	mkdir console_base

Extract the void rootfs from the download ed tarball to 07_rootfs
	tar -xvf void* -C console_base
			
Set a hostname in /etc/hostname
	echo elvis > console_base/etc/hostname
		
Create ~.bashrc with a useful prompt
	echo 'PS1="\`if [ \$? = 0 ]; then echo \[\e[0m\]0\[\e[0m\]; else echo \[\e[0m\]1\[\e[0m\]; fi\` \w # "' > console_base/root/.bashrc
	
Create ~.profile to enable ~.basrc
         echo " . ~/.bashrc" > console_base/root/.profile
         
Check the files with less. Type q to exit less.
	less console_base/etc/hostname      
	less console_base/root/.bashrc
	less console_base/root/.profile

Sometimes it is easier to make edits in a text editor, rather than to write more advanced commands to run in the terminal.
For example:
One could run the following to remove a "#" in order to uncomment the line needed to choose the locale for the US in /etc/default/libc-locales.
	sed -i 's/#en_US.UTF-8 UTF-8/en_US.UTF-8 UTF-8/' /etc/default/libc-locales
But that line is already uncommented in /etc/default/libc-locales, so, if one wanted to choose a different locale, one would have to run
	sed -i 's/en_US.UTF-8 UTF-8/#en_US.UTF-8 UTF-8/' /etc/default/libc-locales      to comment the uncommented line, then run	
	sed -i 's/#lt_LT ISO-8859-13 /lt_LT ISO-8859-13 /' /etc/default/libc-locales    to uncomment the desired locale for Italy.
	
Navigate to console_base/etc with your file manager and open rc.conf with an editor. Look over the defaults and uncomment or construct lines as neccessary 
to set the hardwareclock, timezone and keymap. These settings can always be adjusted later.  https://docs.voidlinux.org/config/rc-files.html
add   FONT="ter-132b"	to line 27 for larger fonts in the console. Other fonts and sizes are in /usr/share/kbd/consolefonts	


The chroot envrionment allows one to make normal file creations, deletions and edits from the termainal just as above, and also allows 
you to run the Void xbps package manager and configuration utilities without having to boot into the install.

Make your Firstrib tools executable.
	chmod +x mount_chroot.sh umount_chroot.sh wd_grubconfig modify_initrd_gz.sh
	
Enter the chroot envrionment. mount_chroot.sh should report "chroot directory is console_base".
	./mount_chroot.sh console_base
	
Set Bash as the default shell for user root.
	usermod --shell /bin/bash root
	
Set a new password for user root. The passwd utility will prompt you same as if you were booted
	passwd

Or remove roots password entirely. (it is presently voidlinux). passwd should return "passwd: password expiry information changed".
	passwd -d root

Update xbps and its repos. If xbps needs to be updated, you will be informed how.
	xbps-install -Su

Install some console and basic apps.
	xbps-install -Su xterm xauth file ntfs-3g zstd wget e2fsprogs rsync squashfs-tools ranger nano NetworkManager terminus-font pulseaudio pulseaudio-utils alsa-plugins-pulseaudio alsa-utils

pulseaudio, NetworkManager and it's dependency dbus, are services that require links to be created if the service is to start at boot.
	ln -s /etc/sv/NetworkManager /etc/runit/runsvdir/default/NetworkManager
	ln -s /etc/sv/dbus /etc/runit/runsvdir/default/dbus	
	ln -s /etc/sv/pulseaudio /etc/runit/runsvdir/default/pulseaudio
	
Leave the chroot envrionment. mount_chroot.sh should report "Cleaning up mounts to chroot directory console_base"  
	exit
		
Run umount_chroot.sh to clean up the host filesystem
	./umount_chroot.sh

Note: At this point in the build, I have had failures to exit chroot properly. The expected message after exiting mount_chroot.sh was not returned. The host has symptoms that the session has become corrupted. The host has an inability to copy, run mksquashfs or determine file sizes.  Further work on your rootfs build will corrupt your build. If in doubt, reboot before making a backup.

Make a backup of console_base
	mksquashfs console_base console_base.sfs
	
If your host does not have squash tools installed. You can back up console_base with
	cp -r console_base console_base.bak	      
	
Rename console-base to 07_something which is required by the FirstRib initrd.
 	mv console_base 07_console_base

Create some boot hints for grub.
	./wd_grubconfig
