Yea. You should probably consult some other programmers first. I'm not sure if it would work if a classic system is already running OS4. OS4 uses different patching functions. By the way, I checked the scripts in the install ISO and it appears that the installer is already adding a post-install script to WBStartup that executes the first time OS4 is started and then deletes inself.

Yes, that's what Rigo also explained above. AFAIR, it deletes itself once you have run the Extras installer (regardless of what, if anything, you install with it), since its purpose is to give you this option.

This functionality shouldn't prevent the solution you proposed, though, nor be harmed by it.

But apart from preventing a reboot, there may be more to look into, as I think the OS installation also inhibits all volumes just before doing the reboot. You'd have to prevent that as well, or you won't be able to do much.

Best regards,

Niels

Since he said he's installing to a hardfile, I don't know if a hardfile can be inhibited or if the filesystem device containing the hardfile would need to be inhibited. Either way, it might be possible to add 'uninhibit' code to the ColdReboot() patch. A further complication might be that the post-install script is added to WBStartup with a very low priority and I'm not sure if AmiKit's script should be started before or after the post-install script (probably after). In my opinion the real "show-stopper" for the whole process is the fact that modifying the Install process puts the responsibility for a clean install (no damage to users system) on him instead of Hyperion.

Well, the OS installer runs under AmigaOS and must be seeing a volume, it doesn't know about such a concept as a hardfile. And yes, I guess you could un-inhibit in a patch, and inhibit again before rebooting (it's done for a reason - making sure all writing has stopped before the reboot; probably most relevant for those who still use FFS).

Very true. I'd steer well clear of messing with all this in practice if it were me - but it's great fun trying to invent theoretical solutions .
