Debug outputting binary data

[helgi]

There are certain commands that should probably not be outputting to the tty.

An example:

2014-01-30 10:02:51,315: 13 default install
2014-01-30 10:02:51,316: label install
2014-01-30 10:02:51,316:    menu label ^Install
2014-01-30 10:02:51,316:    menu default
2014-01-30 10:02:51,316:    kernel ubuntu-installer/amd64/linux
2014-01-30 10:02:51,316:    append vga=788 initrd=ubuntu-installer/amd64/initrd.gz -- quiet
2014-01-30 10:02:51,316: label cli
2014-01-30 10:02:51,316:    menu label ^Command-line install
2014-01-30 10:02:51,316:    kernel ubuntu-installer/amd64/linux
2014-01-30 10:02:51,316:    append tasks=standard pkgsel/language-pack-patterns= pkgsel/install-language-support=false vga=788 initrd=ubuntu-installer/amd64/initrd.gz -- quiet
2014-01-30 10:02:51,316:

2014-01-30 10:02:51,316: Please use a boot loader program instead.
2014-01-30 10:02:51,316: 
2014-01-30 10:02:51,316: Remove disk and press any key to reboot . . .

And then it give me alot of binary data. There is a few others (genisoimage, mcopy, etc) that need to be silenced as well I think. I used to have a list of them somewhere but can't locate it, probably in one of my branches.
