Update to Debian Lenny
When updating to Debian 5.0 Lenny I hit some problems and also found some solutions:
Xen does not work after upgrading.
The problem is, that Xen 3.0 depends on python2.4 but Lenny comes with python2.5. SiD3WiNDR describes two solutions to the problem. I upgraded Xen and Xen Tools:
aptitude install xen-utils-3.2-1
F-Secure Linux Security does not work with Lennys Kernel
F-Secure uses the dazuko kernel model, which is incompatible with kernel 2.6.26 because it uses old Kernel API (I guess). DazukoFS may be a solution as proposed in Ubuntu Forum. While writing this, there is no solution from F-Secure available.
