Fedora 36, --disable-rofiles-fuse mess

[Alec Leamas]

Dear list,

Using flatpak-builder on Fedora 36 is interesting. Using a since long 
working manifest [1] I make a regular build and gets

fuse: unknown option(s): `-o splice_write,splice_move`
[...]
.flatpak-builder/rofiles/rofiles-8qXbpZ not initialized, use flatpak 
build-init".

The same command works on F35. I can work around this using
--disable-rofiles-fuse. While this step works, my next build step 
involves "flatpak-builder --run". This gives me

.flatpak-builder/rofiles/rofiles-8qXbpZ not initialised ...

If I try to add --disable-rofiles-fuse to the --run command it is 
rejected as unknown option

Both F35 and F36 uses flatpak-builder 1.2.2.

Confused. Any clues, out there?
