[Labs-l] List of packages that are supported by tool labs

[YiFei]

My suggestion: Crontab "dpkg -L" (as root or give a specific user/group to run it) on every node and somehow save stdout (and/or stderr) to NFS. And cron a script that process those. And finally have a web script to let people see them.
