#85 Prelink for Performance
HACK
At this point, you have only rebuilt the Debian database such that it
“knows” about only the most fundamental packages you have installed. It
doesn’t know you have things such as KDE installed, or various productiv-
ity applications. These programs are on your system and they will work, but
Debian doesn’t know to upgrade them as new versions appear. The only
way to get Debian to know about the packages you have installed is to
install them again.
Don’t worry. You won’t have to reconfigure the packages you reinstall. But if
you want your Debian package database to know they exist, you have to install
them again. You can install your favorite programs any way you want, but this
suggestion should make the process easier. Install the
synaptic program:
# apt-get install synaptic
Then start up a graphical desktop, and run synaptic from a run dialog or ter-
minal window.
synaptic is a graphical, friendly package installer for Debian
that sorts the available packages by category. You can browse through the
various categories and checkmark all the programs you want on your sys-
tem. Then have synaptic (re)install all of them in one big batch. Voilà. You
have just recovered from one of the most disastrous types of damage one can
inflict upon a Debian system.
