# These units either fail outright or stall waiting for hardware that
# doesn't exist under Apple's `container` guest virtualization: no console
# gettys are attached, no hugepages/fuse-connections kernel interfaces are
# exposed, and (crucially) the guest kernel has no loadable-module support at
# all, so anything that tries to load a module fails immediately. Masking
# them avoids both boot-time stalls and permanent `systemctl
# is-system-running` degradation from units that can never succeed here.
