If I understand correctly. The answer is no. (Unless you write some clever initramfs) Afaik, the kernel takes the entire partition and mounts it at '/'. If you want it to use a directory (which would then be at '/newinstall') you need to get the kernel to chroot into that directory and run init in there. Only option I see is to use an extra disk. Maybe a USB drive and use that. -- Joost -- Sent from my Android device with K-9 Mail. Please excuse my brevity.
