Infrastructure Software

I have several questions regarding Linux Kernel and Oracle Linux patching.

Oracle Linux Release 5 update 2
2.6.18-92.1.22.0.1.el5 (x86_64)

Linux Kernel Versioning
2.6.18-92.1.22.0.1.el5
2. = major Number
.6 = minor number
.18 = patch level
-92. = package version
-92.1.22 = Red Hat patch level
.0.1 = Oracle patch level

Question 1:
Is the Linux Kernel Version above correct in my understanding of its construction?

Question 2:
Given your at Oracle Linux Release 5 update 2, if you apply only security patches to this version will only Oracle patch level increment? Please explain how it increments?

Question 3:
Given your at Oracle Linux Release 5 update 2, if you apply all bug fixes and security updates to this version will only the Oracle patch level increment? Please explain how it increments?

Question 4:
Given your updating from Oracle Linux Release 5 update 2 to Oracle Linux Release 5 update 8, will the only the Red Hat patch level and Oracle patch level increment? Please explain how it increments?

Question 5:
If not previously addressed, how is the version incrementing different for security fixes, bug fixes and updates (Oracle Linux 5 update 2, update 3, update 4 etc.)?


Thank you very much.
