I'm using boinc with Pardus. It's very easy. Just download boinc from
http://boinc.berkeley.edu/download.php and put it in your homedir.
You can install it by making the downloaded file executable and then run it:
chmod +x boinc_5.8.16_i686-pc-linux-gnu.sh
./boinc_5.8.16_i686-pc-linux-gnu.sh
and answer the questions you'll get.
To start boinc automagicly after each (re-)boot of Pardus you can put the next at the end of the file /etc/conf.d/local.start:
cd /home/<username>/BOINC
./boinc 1>&2 &
instead of <username> you should fill in your username.
You should edit the file local.start as root (a "normal" user can't edit it).
