As it seems that creating a GTK terminal widget usable with DFB is not
something is going to be done in short time ( and removing "Execute a
shell" form main-menu is not the optimal solution, as proposed in the
plan for tomorrow's d-i meeting ) i propose this patch to
d-i-utils-shell.postinst from debian-installer-utils package

when the user presses "Execute a shell", the "chvt 2" command is run and
the console is switched to VT2.
As the original chvt tool from console-tools depends from a couple of
libraries, i've rewritten it (source code attached below) taking source
code from the original console-tools package.
I've tested this solution and it works well; we should also provide a
way for the user to get back to the VT where the g-i runs, as actually
he's told to press run "exit" to get back to the instalation even if the
GTK frontend i used.
If the patch is accepted, someone should also choose where to place the
chvt.c sourcecode.
