using schroot in debian.org porterboxes
=======================================
+When logging into Debian porterbox machine, it should display similar message:
+
+<pre><code>
Welcome to porterbox.debian.org, the Debian arch porterbox.
See 'schroot -l' for a list of available chroots. Start new sessions
to list (your) open sessions.
This server is hosted at data centre.
+</code></pre>
+
+The previous description is rather compact and dense, so let's try to describe the usage in more friendly way.
+
+* List available chroots:
+
+ $ schroot -l
+
+* Begin a persistent schroot session on Debian unstable:
+
+ $ schroot -b -c sid -n mysid
+
+* Update and upgrade Debian unstable chroot:
+
+ $ dd-schroot-cmd -c mysid apt-get update
+ $ dd-schroot-cmd -c mysid apt-get upgrade
+ [..]
+ Do it for real [Y/n]: <Enter>
+ [..]
+
+* Install your broken package build dependencies:
+
+ $ dd-schroot-cmd -c mysid apt-get build-dep gentoo
+ [..]
+ Do it for real [Y/n]: <Enter>
+ [..]
+
+* Change root to Debian unstable chroot:
+
+ $ schroot -r -c mysid
+
+* Download your broken package source:
+
+ (sid_arch-dchroot)user@porterbox:~$ apt-get source gentoo
+
+* You should be able to reproduce your issue, hack on the package, fix the bug. Once you are done with your work, please, finish your schroot session:
+
+ (sid_arch-dchroot)user@porterbox:~$ exit
+ $ schroot -e -c mysid
+ $ exit
+* You should be done by now. If you find any issue, please report to debian-admin@lists.debian.org.
