update-binfmt should remember which packages were disabled

[Mathias Hasselmann]

Binary package hint: binfmt-support

Ubuntu's binfmt support is pretty nice, but it comes into your way when cross-compiling alot. As it is some frequent error source for me I'd like to disable the cli and the wine detector on startup, but be able to easily re-enable them by calling "update-binfmt --enable cli". Currently I have to add "update-binfmt --disable" statements to my local.rc file, as update-binfmt doesn't remember enable/disable requests and as it doesn't provide any configuration files.

Ilkka Tuohela (aka hile) suggested to add some ENABLED/DISABLED variables listening which formats to enable/disable to /etc/defaults/binfmts-support. Leaving them empty would enable all formats.

How about something like 'update-binfmts --save --disable <name>'?

(Not that that exists yet, but as an interface suggestion ...)
