So at any time, the same user logged in from different machines might get the PAC with the same version number but with different expiration times.

因此，在任何时候，相同的用户在不同的机器上登录会得到相同的版本号，但是超期时间不同。

For instance, if a Linux binary were to try to call uname to get a kernel version, it would be very confused if it got back a NetBSD version number.

例如，如果Linux二进制程序尝试调用uname来得到内核版本，却得到了NetBSD的版本号，这将非常令人迷惑。

Please don't read too much into the pace of version number changes - they just mean we are moving through release cycles and we are geared up to get fresher releases into your hands!

请不要对我们的版本号变化太快产生误解——这只是意味着我们正在通过发布周期，将新鲜的版本送到你们手中。
