Nope - from man fopen

“w” Open for writing. The stream is positioned at the beginning of
the file. Truncate the file to zero length if it exists or
create the file if it does not exist.

Right but that's not the reason the whole thing did nothing *after* I

Can't you "snap" one of these in half?

And how much other stuff ???

/etc/networking worked JUST FINE and is hugely documented

There was NO reason to change.

So, basically, you now have to BREAK Deb to get it to work
like it used to. Cannonical led the way toward STUPID changes
and now Deb seems to have even exceeded THEM.

I'm gonna look into Arch ......

Um ... TRY that. Neither /etc/network or WPA_supplicant
or dhcpcd.conf are used any more by any sort of default/
fallback.

For a GUI-less Bookworm you have to fool with the very
horrible 'nmcli' and then manually EDIT the net def
templates it creates way down in /etc/NetworkManager/
system-<something>

Bookworm is just HORRIBLE in this respect on a Pi.

Gonna check into Arch - seriously check into it. IF IT
WORKS *DON'T BREAK IT*
