# Each label carries a `platform:` filter, so a macOS host never evaluates
|
||||
# the Windows/Linux queries and vice versa. Ring names are OS-prefixed
|
||||
# because label names must be unique across the whole file. "Ring 1" alone
|
||||
# would collide across platforms. Only running one OS? Delete the other two
|
||||
# platforms' blocks below; nothing else in this file depends on them.
|
||||
#
|
||||
# `platform` choices are `darwin`, `windows`, `ubuntu`, `centos`. There is
|
||||
# no bare "linux" value, so Linux rings list `ubuntu,centos` to cover both
|
||||
# distro families in one label.
