The #0 represents how many times that kernel has been compiled.

If you manually compiled the kernel, the first time installed it would be #0. If you recompiled it and reinstalled, it would then show #1. Recompile and re-install, and it will show #2. And so on.

The number in front of the kernel name (4.5) is the OS version.

In BSD land, the OS version and the kernel version are always the same, as they are developed as a single, integrated unit (you don't "upgrade the kernel" without also upgrading the entire OS).

When you config(8) a kernel, it is assigned a version number, which will start with zero if this is the first time, or if you have delete the /usr/src/sys/arch/<ARCH>/compile/<KERNEL> directory structure. After that, the version number will increment each time.

There are several ways to see your kernel. For more complete information than uname(1), use either
$ sysctl kern.version
or
$ dmesg | head

Read & study Section 5 of the FAQ:

http://openbsd.org/faq/faq5.html

Huh? The information is quite exact.

  • If you are running 4.5-release, there is no reason to rebuild the kernel
    unless patches require it. Information on patching can be found at the following:

    http://openbsd.org/errata45.html

    More information on patching can be found in Section 10.15 of the FAQ:

    http://openbsd.org/faq/faq10.html#Patches
  • If you are running -stable, keep track of published errata & rebuild as necessary. Building the kernel, userland, & Xenocara is all covered in Section 5 of the FAQ.
  • As for 4.5-current, rebuild when features or changes warrant it. Again study Section 5. Also, be very aware of the information found in the Following -current document.
All of your questions of late are valid, but they are covered in detail in the FAQ. Seriously study this document. It is maintained by developers of the Project for a reason -- to be correct, current, & answer questions which most users will ask at one time or another.

As an addendum (& repeating information I've already covered in a different thread...), 4.5-current no longer exists given that the OPENBSD_4_6_BASE CVS tag was created nearly a month ago. The head of CVS is now 4.6-current.
