This workshop, intended for very senior administrators, provides an informal roundtable discussion of the problems facing system administrators today. Attendance is limited and based on acceptance of a position paper (plain ASCII, three paragraphs maximum); a typical paper covers what the author thinks is the most difficult or important issue facing system administrators today, why this is a problem, and why this problem is important. A more complete description of the workshop and information about position papers is available at atw.menlo.com. Position papers should be sent to lisa12ws-atw@usenix.org. Attendees are required to bring a laptop.
