[$] Limiting the power of package installation in Debian

<p>There is always at least a small risk when installing a package for adistribution. By its very nature, package installation is an invasiveprocess; some packages require the ability to make radical changes to thesystem-changes that users surely would not want other packages to takeadvantage of. Packages that are made available by distributions are vettedfor problems of this sort, though, of course, mistakes can be made.Third-party packages are an even bigger potential problem because they lackthis vetting, as was discussed in early October on the debian-devel mailinglist. Solutions in this area are not particularly easy, however.
