I know there are some .APK apps that do it, but none seems to work for me (but if you have any suggestions, I'll try).
I have LineageOS on my PC. So, my question is How to make a bootable stick with in Termux?
Which commande should I install?
I have also installed some proot-distros installed (I'm currently testing them as a newbie), so, could I use one of them? Should I try to use Multisystem?
I had good success with Multisystem, so if I could use it either as their bootable ISO or their .deb with success, if you think it's possible, I'll listen to your suggestions.
EDIT: As asked, I add some precisions about my goal. I'm trying to install a Multisystem ISO (or as a .deb package) Installation inside a distro, as a .deb package: http://liveusb.info/dotclear/index.php?pages/install Multisystem as an ISO here: https://sourceforge.net/projects/multisystem/files/iso/
I need to resize my /system partition, and If I can, create a /recovery partition, so I need to use Gparted ISO. And on the same USB, I need Also a recovery if my AndroidX86 fails to start. So I decided to install Multisystem to make a multi-ISO stick.
