PER_ALWAYSZnoblockZ cc_resizefsZResizefszResize filesystema Resize a filesystem to use all avaliable space on partition. This
module is useful along with ``cc_growpart`` and will ensure that if the
root partition has been resized the root filesystem will be resized
along with it. By default, ``cc_resizefs`` will resize the root
partition and will block the boot process while the resize command is
running. Optionally, the resize operation can be performed in the
background while cloud-init continues running modules. This can be
enabled by setting ``resize_rootfs`` to ``noblock``. This module can be
disabled altogether by setting ``resize_rootfs`` to ``false``.z@resize_rootfs: false # disable root filesystem resize operationzAresize_rootfs: noblock # runs resize operation in the background)idnametitle descriptionZdistrosZexamplesZ frequencyZactivate_by_schema_keysc C s t j| r0tjjd| r0ddddd| g}ndddd| g}t jjd}t jjtjddgd jd d j }||kr|j
