I have a solution that works well. For it to be incorporated into stretch a new udeb would be needed, an extra option added to the installation menu, and two simple additions to debian-cd's CONF.sh.
The modifications to CONF.sh From export i386_MKISOFS_OPTS="-as mkisofs -r -checksum_algorithm_iso md5,sha1” export amd64_MKISOFS_OPTS="-as mkisofs -r -checksum_algorithm_iso md5,sha1” to export i386_MKISOFS_OPTS="-as mkisofs -r -checksum_algorithm_iso md5,sha1 –modification-date=2732101000000000" export amd64_MKISOFS_OPTS="-as mkisofs -r -checksum_algorithm_iso md5,sha1 --modification-date=2764101000000000" The modification date of the usb stick is read as the UUID of the stick. 2732 (the supposed year) indicates a 32bit architecture. 2764 indicates a 64 bit architecture. The final 00 indicates x86_xx. The line UUID=2764-10-10-00-00-00-00 /media/cdrom0 auto defaults,auto,user,ro,nofail 0 0 is added to fstab The file 99-mount.rules is copied to /etc/udev/rules.d this file consists of the line SUBSYSTEM=="block", RUN+="/bin/mount UUID=2764-10-10-00-00-00-00" The finish-install udeb has been high-jacked and has been modified to implement these additions. This example uses 64 bit. 2732 would be used for 32 bit. How this works. Assuming a machine that has been installed from a 64 bit usb stick. If a stick with a UUID=2764-10-10-00-00-00-00 is inserted then it will be mounted as an optical disc. Any other UUID will be ignored. If a 64 bit stick of a later release (stretch) is inserted then it will be mounted as it will have the 64 bit UUID. The grub splash-screens are replaced to identify the modified systems. The jigdos for these sticks (including DVD sized versions) can be found at http://www.copyleft.co.nz/download.html. I can send a copy of 'finish-install_3.3stick-64_all' to anyone who is interested.
