Add files to bootable USB-Stick


I created an USB-Stick from the downloaded Qubes-Image. I tried to add files on the stick for using them after booting the rescue-system. Is this possible?

Doesn’t it automatically mount as read-only?
It may fail integrity checks if you add files, maybe it doesn’t matter to you though.

It would perhaps be better to use a separate usb stick.

Yes, it is mounted as read-only. There are 2 partitions on the USB-Stick. I can mount them manually as read-write and add files. After booting from the USB-Stick to the rescue-system the files are lost / I can’t find them.

I followed the description from
to add a new partition to the USB-Stick.

The command
sudo mke2fs -j /dev/sdX3
ended with the error message:
ext2fs_mkdir: Eingabe-/Ausgabefehler beim Erstellen des Wurzelverzeichnisses

After that the stick was not usable.

I recreated the ISO-Image to add files to the USB-Stick.
