During support of Open Enterprise server, a customer proposed that we include the maintenance patch level as well in the /etc/novell-release file
So for example
cat novell-release
Novell Open Enterprise Server 2015 (x86_64)
VERSION = 2015
PATCHLEVEL = 0
could look like this
cat novell-release
Novell Open Enterprise Server 2015 (x86_64)
VERSION = 2015
PATCHLEVEL = 0
MAINTENANCE_PATCH = 201603
