Weird debootstrap output

Hi *,

I am currently fiddling with debootstrap as I am building my own
installer for a stripped down Debian router system. My problem is that
debootstrap is freezing my terminal and I can't find out why. I captured
the output and catting it to an xterm yields the same result.

Interestingly it works fine on the Linux console and inside screen
as I just noticed. I still would like to know what's breaking xterm
in this output so if somebody wants to help or is curious please
have a look at

http://people.debian.org/~torsten/debootstrap.capture

Any hints appreciated.

Thanks

Torsten

Primary suspect: an escape sequence doing something weird to your
terminal. And indeed:

$od -Ax1 -tc debootstrap.capture | grep -B5 '\<033\>'
006f90 . 6 6 - 1 ) . . . \n \n S e t t
006fa0 i n g u p c o n s o l e - t
006fb0 o o l s ( 0 . 2 . 3 - 2 3 . 3
006fc0 ) . . . \n L o o k i n g f o
006fd0 r k e y m a p t o i n s t
006fe0 a l l : \n N O N E \n 033 ] R \n S e
$

Looks like the console-tools setup produces an escape sequence.

Ciao. Vincent.

Yes, the terminal do not freeze, it just ends up white on white. I've
seen it several times, bug have no idea what is happening.

It was reported as bug #115699 and believed to be fixed, even if
no-one understood what was going on.

For me it just stops doing any output, scrolling or whatever. More
interestingly the processes just disappear but do not seem to finish.
Using "2>&1|tee foobar" helps but that's hardly a solution. Running it
in screen works as well.

Silly. Weird. More coffee ;)
