+# RHEL_RELEASE
+# -------------
+#
+# Represents build number in 'release' part of RPM's name-version-release.
+#   name is <package_name>, e.g. kernel
+#   version is upstream kernel version this kernel is based on, e.g. 4.18.0
+#   release is <RHEL_RELEASE>.<dist_tag>[<buildid>], e.g. 100.el8

+#
+# Early y+1 numbering
+# --------------------
+#
+# In early y+1 process, RHEL_RELEASE consists of 2 numbers: x.y
+# First is RHEL_RELEASE inherited/merged from y as-is, second number
+# is incremented with each build starting from 1. After merge from y,
+# it resets back to 1. This way y+1 nvr reflects status of last merge.
+#
+# Example:
+#
+# rhel8.0                        rhel-8.1
+#   kernel-4.18.0-58.el8   -->     kernel-4.18.0-58.1.el8
+#                                  kernel-4.18.0-58.2.el8
+#   kernel-4.18.0-59.el8           kernel-4.18.0-59.1.el8
+#   kernel-4.18.0-60.el8
+#   kernel-4.18.0-61.el8   -->     kernel-4.18.0-61.1.el8
