linux-dev is a list for development of the SIPB port of the Athena environment to Linux, and also for other Linux-related matters appropriate for the SIPB members active in supporting Linux. This is a medium-volume list.
linux-help is a list for users to send questions about Linux to. It's primarily for questions about the Athena port, but other questions are also reasonable. Most questions to this list get answered fairly quickly. This is a pretty high-volume list.
linux-athena is a list for announcements about the Athena port. This is a public list; everyone who uses the Athena port or wants to receive announcements about it can add themselves. Currently, this list is just getting started, and isn't advertised all that well. It is expected to be a low-volume list.
