Hi Adam,

You're right. We didn't answered you question...

I basically agree.

Just one note : what would happen if the kernel panic (let's say there's no GEM 
or INIT line in MINT.CNF, or an unrecoverable bus error occurs in the kernel 
code) and displays an error message. It still needs a way to halt the computer, 
so user can see what went wrong.

So FreeMiNT still needs a way to stop the computer without powering it off. But 
this code could be private to the kernel and not usable from user mode.

So, yes, Halt can mean Poweroff as long as the kernel still can use 
a "Realhalt" mode.


Oh, and check that FreeMiNT issue a command to every hardrive to instruct them 
to save their write cache and waits for confirmation before powering off. Or 
you may run into problems. Having to poweroff manually used to allow enough 
time to hardrives for saving datas, so nobody could have notice this before...


Best regards,
