 '''NOTE:''' The buildslave needs root access to be able to connect to the t_client.sh test servers using OpenVPN. Moreover, anyone who controls the buildmaster can do whatever he wants on the buildslaves by simply modifying the build procedure. For this reason you should only run buildslaves on expendable virtual machines. That said, you can grant limited ''sudo'' privileges to a normal user to run buildbot as a normal user: see section "Running builtbot as non-root user" for details.

+= Creating a VM for the buildslave =
+
+A Linux VM will probably need at least 768MB of memory. Some distros such as Fedora 24 suggests 1024MB as the bare minimum. The VM should have at least 8GB of diskspace, but adding a bit more helps avoid problems later on.

 This method is  a bit hackish but works fine.

+== Buildslaves running out of disk or inodes ==
+
+The buildslaves consume large amount of diskspace and inodes:
+
+{{{
+$ df -m|grep -E '(^Filesystem|vda1)'
+Filesystem     1M-blocks  Used Available Use% Mounted on
+/dev/vda1           9196  4342      4365  50% /
+
+$ df -i|grep -E '(^Filesystem|vda1)'
+Filesystem     Inodes  IUsed  IFree IUse% Mounted on
+/dev/vda1      606208 274616 331592   46% /
+}}}
+
+Because buildslave leaves obsolete build directories laying around, removing them can help free up some space and inodes:
+
+{{{
+$ rm -rf /var/lib/buildbot/slaves/openvpn/build-*
+}}}
+
+On Ubuntu it is fairly important to remove useless kernels and kernel headers periodically:
+
+{{{
+$ apt-get autoremove
+}}}
