Yes, the start.elf installed by the upgrade procedure is retrieved from within the SYSTEM file (/usr/share/bootloader/start.elf) so you'll have to unsquash/squash the SYSTEM file before applying the update.

You could always add something to autostart.sh which compares /flash/start.elf with /usr/share/bootloader/start.elf (ie. md5sum) and if they're the same then you can patch /flash/start.elf and reboot. The next reboot will see that the two files are no longer the same and continue as normal.

I must ask though - why are you patching start.elf? I'm not sure what problems this could cause, and might not be a good basis when reporting problems as you're no longer using the stock firmware.

Thanks for the info, I’ll give the startup script a try as will be quicker than unpacking/repacking SYSTEM.

When reporting bugs I do test on stock firmware 👍
