I figure "4.1/4.1.11a" is the mysql version number, and "4sarge4" is specific to Debian? But what do the numbers before and after "sarge" signify? When is the number before/after incremented? ie when do we get 5sarge4 or 4sarge5? Can I assume that mysql-server-4.1/4.1.11a-5sarge4 or mysql-server-4.1/4.1.11a-4sarge5 would already contain the same fixes? > Actually, mysql-server-4.1 is the name of the package. The 4.1 is simply there so that the name can distinguish it from the mysql-server-5.0 package, for example. The version is 4.1.11a-4sarge4. In any Debian package, the Debian-specific part of the version is anything after the last hyphen. So, 4.1.11a is the upstream version number and 4sarge4 is the Debian part. Generally, Debian packages have numbers like -2, -5.1 or something like that. Now, in the case of a stable release update (for security fixes) there needs to bo a way to make sure that it won't prevent a newer version from overwriting it when the whole OS is upgraded. So, barring any other updates from upstream, if a security fix is released, the first time it changes the version from 4.1.11a-4 to 4.1.11a-4sarge1. Now, the maintainer uploads version 4.1.11a-5 to unstable. When you upgrade the OS, you want the -5 package to be able to be considered "better" than the version from stable.
