Bug#398404: Update on pbuilder support for target distribution

[Osamu Aoki]

Hi,

I have been locally making modified pbuilder which supports all Ubuntu
and Debian.  It is getting some success.  Missing support of sarge in
cdebootstrap is a problem I found in this course.  

Now, everything happens under /var/cache/pbuilder/<mode> for
each --mode option.  

This should address: 373807 272354 

Unlike classic pbuilder, --mode option always upate apt-line (or entire
/etc/apt/*) contets overwriting with
 * /usr/share/pbuilder/<modename>/apt/*,
 * /etc/pbuilder/<modename>/apt/*,
 * ~/.pbuilder/<modename>/apt/*,
in this sequence.  If no <modename> configuration found,

As for pbuilderrc files under --mode option
 * /usr/share/pbuilder/pbuilderrc,  (common for all --mode)
 * /etc/pbuilder/<modename>/pbuilderrc,
 * ~/.pbuilder/<modename>/pbuilderrc,
are read but the <modename> directory based configurations ovride some setting.

(hook may need a bit more integration)

I needed to "dpkg -i ubuntu-keyring_2008.03.04_all.deb" and packahge
modification.  It know a bit of cleaning though.  I upload current one to

    http://people.debian.org/~osamu/package/

Here is how it works, e.g., hardy. (packages properly chacked by gnupg
all the time.)
