The welcome page is the only page using absolute positioning for the newt
components, so that the page occupies all the screen space. This is becoming
too hard to manage, so switch to grid management like elsewhere, even if the
result is less appealing.
Also add an info text to the page with a mention on how to switch back to the
original installer.
* gnu/installer/newt/welcome.scm (run-menu-page): Use a vertically stacked
grid instead of hard window placement.
Source /etc/environment just before starting the installer. The login program
is supposed to load the environment variables of this file through PAM, but as
we replace it by the installer, they are no longer available. This is mostly
useful for the LANG environment variable.
* gnu/installer/build-installer.scm (installer-program-launcher): New exported
procedure.
* gnu/system/install.scm (%installation-services): Restore most of the origin
code. kmscon is only started on TTY1, and the graphical installer is the
login-program.
* configure.ac: Require that guile-newt is available.
* gnu/installer.scm: New file.
* gnu/installer/aux-files/logo.txt: New file.
* gnu/installer/build-installer.scm: New file.

VT for all tty.

account.
