The OSRelease combiner uses the following parsers to try to identify if the current host is installed with a “Red Hat Enterprise Linux” (RHEL) system.

It provides an attribute is_rhel that indicates if the host is RHEL or not. It also provides an attribute release which returns the estimated OS release name of the system, “Unknown” will be returned by default when cannot identify the OS.

  • TODO:

    The lists of keywords to identify NON-RHEL system of each sub-combiners are
    based on our current knowledge, and may be not sufficient. It needs to be
    updated timely according to new found Linux Distributions.

Bases: object

A Combiner identifies whether the current Linux a Red Hat Enterprise Linux or not.

property is_rhel

Returns True if it’s RHEL, False for NON-RHEL.

property is_rhel_compatible

Returns True if Convert2RHEL could convert

property name

Returns the name of the OS. Generally it’s the NAME of the /etc/os-release file, or it’s the same as the release when the /etc/os-release is not available.

property product

Alias of release. Keep backward compatible

property reasons

Returns a dict indicating why the host is a NON-RHEL. Empty when it’s an RHEL. The keys include:

kernel (str): the kernel package
build_info (str): the kernel build information
release (str): the release package
faulty_packages (list): the packages that are not signed and not
    provided by Red Hat
reason (str): a string when nothing is available to check
property release

Returns the estimated release name of the running Linux. It’s RHEL or one key of the OTHER_LINUX_KEYS when it’s NON-RHEL.
