I have just converted a Fedora Core 5 server to a CentOS 5 Xen Dom0 with Fedora Core 5 as a DomU. The process took a little longer than expected because I didn’t have console or network access to the DomU initially. It turned out that /etc/modprobe.conf was configured to have the tg3 device for […] After having read Brice Goglin’s post about what to expect in X for Lenny [1] the thing that seemed most exciting is the support for Multi-Pointer X [2].

The designs feature a graphical representation of MLS security and a variety of text about SE Linux.
