I'm not sure of the terminology but I'm currently running 11 on a beefy workstation. I have a blank 109G partition on my SSD and I want to install 12 on it, but while running 11. I don't want to go thru the trouble of making a netISO USB and booting the install program for 12 off of it. Mainly because I'd like to continue to use the machine during the installation process.
Theoretically I should be able to run the install program, download and install all the packages, and then the existing grub-config should see the new OS on discovery and present it as a boot option while not touching the previous version.
IS there an existing canned process for running the "next version install program" while online and restricting its operations to a single disk/partition?
potential pitfalls:
* reliance on the newer kernel version during install?
* possible contamination of the existing debian pkg database
* install program relocating the grub stage 1 bootloader somewhere else
* post-install scripts not being resilient enough to run correctlyunder a "previous version" with "current version" target disk
IS this a "well supported" installation use case?
