I have remote machine with OpenSUSE, and I cant interact with it only by SSH. I want to install Debian to this machine, how can I do it? I search answers, but each of them assumes, I have physical access to machine to launch setup, and this is something I'm not able to do. I already have USB flash drive inserted into remote machine. Can I, for example, install live system and chroot to it, or reconfigure bootloader to boot from flash, then re-install existing system?
