# These variables represent groupings of functionality in the CNCF
# landscape. In particular, they are areas where there is a choice
# between more than one implementation or an area where abstraction
# is beneficial.
#
# The contents of the variables are are runtime components that
# recipes may use for RDEPENDS.
#
# Build dependencies are not typically flexible, so do not currently
# have DEPENDS equivalents for the components (i.e. DEPENDS on runc
# versus crun).
#
# Distro features such as kubernetes or other container stacks
# can be used to set different defaults for these variables.
#
# Note: these are "global" values, since they represent choices.
# If more than of a grouping is required on target, then the variable
# can be appended or set to multiple values. That being said, Recipes
# should generally agree on the values, hence the global namespace.
# Recipe specific choices can still be done, but they risk
# conflicting on target or causing runtime issues / errors.
