   * The other is that one does not know what is executed on one's own machine since a foreign binary is downloaded. This is helped by the redistribution of selected scientific applications as additional Debian packages - everyone can inspect also their source code and build the packages in an automated way.
  The motivation to create packages for this worthwhile cause requires no further explanation, maybe except for the following hint: Debian is special for its support of many different architectures, which is only sustainable because of an automated compilation of novel packages. Thus, the provision of BOINC on Debian significantly contributes to the acceptance of the project in all these non-mainstream architectures.
  
+ Another peculiarity of Debian is the option to create dedicated chroot environments, which may be essential for security-sensitive administrators. Debian's [[Debootstrap|debootstrap]] tool creates such easily, also in subdirectories of other Linux distributions, and [[Schroot|schroot]] is a good tool for managing chroots. Together with the dynamic package management, this renders Debian a prime candidate for the creation of virtual hosts with arbitrary Linux distributions or - maybe more interestingly - on Windows machines running [[Xen]], [[http://www.colinux.org/|coLinux]], [[VirtualBox]] or [[VMware]]. Also, the frequently distributed [[LiveCD]]s of Debian may help bringing functional BOINC installations to the masses.

+ === Statistics ===
+ 
+ Work performed with the help of the Debian packages counts in the same way as if the upstream client was used. The scientific application for SETI, also available as a Debian package, may even be slightly faster than the original since our version does not waste cycles on feeding the graphics. This paragraph is about the adoption of the Debian package by the community.

- Some users of Debian install the package DebianPkg:popularity-contest. It sends anonymous statistics on package usage to a [[http://popcon.debian.org|dedicated site]]. Follow

- for an overview on the installation rates of boinc-associated packages in Debian. You will find the boinc packages to have a much steeper curve than most regular packages, i.e., these are installed more frequently than the number of Debian users grows. In terms of user adoption we are competing nicely with a couple of other prominent packages and about every 75th installation of Debian features the BOINC client. The latest numbers are retrievable also in the shell:
