Revision 1.1, Fri Apr 6 23:48:53 2012 UTC (6 years, 2 months ago) by riz
Branch: MAIN
CVS Tags: yamt-pagecache-base4
Branch point for: yamt-pagecache

Implement a post-install configuration menu, as proposed on tech-install.
Enables the user to configure a few additional items, including using
pkgin to manage binary packages, in a post-install menu which replaces
the series of questions (Do you want to set a root password? etc).

This is by no means a perfect solution, nor should it discourage anyone
from working on more sweeping changes to sysinst.

Some bug fixes, and .de translation provided by Julian Fagir.

XXX .es, .fr and .pl translations still needed.  Please help!
