Plans for upgrading Fritz to Debian Squeeze

1. Preliminaries

Release Note Information of Upgrading From Lenny.

2. Installation environment

1. su to root, start a screen session (preventing partial upgrade issues if the network connection drops)

2. Open a physical console root login just in case

3. Installation Steps

3.1. Upgrade Kernel and udev

1. Install new kernel image and openafs-module-dkms

2. Install udev

3. Reboot

3.2. Basic Upgrade

1. apt-get upgrade

2. Reboot?

3.3. Full Upgrade

1. apt-get dist-upgrade

2. Reboot?

3.4. Clean Up

1. Make sure the other machines are still sane after losing volume access for a while.

4. Caveats

4.1. pam_unix_session locking all login access

This bit us on hopper. ClintonEbadi has confirmed this is not an issue on fritz.

4.2. Locally built packages

Todo: someone needs to scan fritz for locally built packages (krb5 and openafs?) and make sure we have an upgrade path for them.
