(bbbush) 在提交 Bug 和交流时一般都需要提供 Smolt 公开 UUID。请提交自己的配置信息到 Smolt 数据库，并公开自己的 “Smolt 公开 UUID”(smolt public UUID)。提交信息的方式是：安装 smolt (yum install smolt)，在命令行以 root 用户运行 smoltSendProfile，在看到提示“是否发送”时选择“是”。查看自己的 Smolt 公开 UUID 的方法是：安装 smolt，运行 smoltSendProfile，发送配置信息，发送完毕时会得到一个 URL 和一个密码。Smolt 公开 UUID 就包含在 URL 中，类似 “pub_5f5f36a3-b03d-4e98-90d2-37dfca75985b”。Smolt 公开 UUID 总是以 “pub_” 开始，值与 /etc/sysconfig/hw-uuid 不同，但有关联。

原文见 Is Smolt the Key to Counting Linux Users? by Rahul on Fri 7th Nov 2008 16:17 UTC

Smolt is a opt-in hardware profiler developed by Fedora Project and now adopted by OpenSUSE and in consideration by Ubuntu as well. While originally developed for understanding commonly used hardware, InternetNews looks at the potential for Smolt to be a tool to count Linux users. “Smolt could also potentially be a tool for counting the total number of users for a given platform, though that’s not its ideal use case. The Linux Foundation’s Ts’o noted that Smolt probably wound not be that great for counting Linux users as a whole. Fedora’s Frields agreed, noting that Smolt is probably not as good for counting users as it is for counting proportional use of hardware across the user base. ‘We prefer to count users with other methods, which we document on our wiki openly and transparently,’ Frields said.”
