Fedora 11 upgrade
Some relatively new Linux documents that should be reviewed:
- http://docs.fedoraproject.org/security-guide/ - an introduction to system security for Linux systems.
- http://docs.fedoraproject.org/selinux-user-guide/ - the MISSING document! One of the challenges with SELINUX has always been a lack of adequate documentation. SELINUX has been a pain since it was introduced – things ‘quit working’ and after some period of time you find that SELINUX is getting in the way… What’s the real problem? IMO SELINUX was put in place without adequate documentation – both conceptual docs as well as real-world-how-do-I-use-it information. When I started searching for more information (a few years back) I could only find slides/papers from seminars – no real, helpful, conceptual documentation. Will this document fix SELINUX problems? No – however if you read it then the resolution process should be clarified; perhaps programmers will read it and assure that their software follows good steps to avoid SELINUX hassles?
FC9 to FC11 upgrade
- Hmm, Anaconda having problems with my storage – resizing partitions to create a new drive for this install.
- Gui installer crashes regardless of disk options selected – trying text mode…
- No luck – went to Bugzilla and found post suggesting dis-abling USB. Install possible (without mouse) after doing so.
- About 1 hour to upgrade ~1500 packages and reboot.
- Some Grub tinkering required since I have many partitions
Next, Upgrade Virtual Box
- Quick but sound not working?
- Also, OS seems to be thrashing a bit? (relatively heavy load compared to FC9)
- After a quick visit to the VirtualBox forums I get a hint that the new sound card driver may be the issue; I un-install-re-install sound driver and things settle down. However, the system load is higher than with FC9 – note that I do like ’sharing’ my sound card between Linux and Virtual Box instances so I will probably keep this configuration.
Next, try Cobbler with FC11
I install Cobbler (Bare metal/virtual system provisioning solution – see other posts on this site) and give it a whirl. Whoops – my network config no longer works for Cobbler and Virtual Box. This may take some time to resolve… VirtualBox has been great for me but changes to it’s networking processes have created some challenges – last year some handy ‘bridge tools’ were removed from the package. I confirm that all is well with the Cobbler setup (web ui works, firewall adjusted, repository created, base system added, Selinux changes made, etc.) When I boot the virtual machine (via VirtualBox) it cannot ’see’ the TFTP server. Hmm – I decide to wait for the next release of Cobbler (should be fall of 2009) to work through this problem [noting that this could also be a VirtualBox networking issue...]
