Unfortinately I was not allowed to make comments longer than 140 signs. So I respond here.

From the psychological point of view there is a big problem in cognition that does not simplify the issue. The image of the sexes is biased. A traditional man fits the image of a leader. Strong, self-confident, …
The problem is a woman having those qualities. She migth be a good person for a leadership position. Unfortunately her character traits are not fitting the traditional image of a woman anymore. Leadership for women – as far as I can comment on that – is a balancing act. Unfortunately.

As long as those biases exist. I do not see any solution.

Here is what I did:

sudo mkfs.vfat -n MultibootUSB /dev/sdd1
sudo mount /dev/sdd /mnt/
sudo grub-install --no-floppy --root-directory=/mnt /dev/sdd

All iso files have to put to ‘/mnt/iso’.
My config file ‘/mnt/boot/grub.cfg’ can be downloaded here.

Especially the configuration for Arch Linux was a bit tricky to create.
‘archisolabel’ has to be the label of the image file used.
‘img_dev’ is set to the uuid of the usb device used.

Quite interesting is also the remastering of certain files. I put the neo keymap into /arch/any/usr-share.fs.sfs.

See here: https://wiki.archlinux.org/index.php/Remastering_the_Install_ISO. If anybody wants to have the iso file, just tell me.
