Installing Linux Lite via a systemback ISO to a different laptop

[Moltke]

THanks Moltke this sounds promising!

One thing I’m not sure about is the aptik- am I correctly understanding that once I am using the LL live I update the live OS with everything I want then use aptik to make a backup THEN use systemback to convert that aptik backup to an ISO?

No, aptik will create a couple of files with the system info you've decided to save, save those files somewhere else, i.e a usb stick, create your live .iso with systemback, burn it to a usb and when installing in another laptop plug the usb stick where aptik's files are in and use them to install and make all the customizations and personal configurations you need to.
