pick the device to format automatically

lsblk supports JSON output with the -J flag, and we have yq installed, so we can do quite a bit with it.

Examples:

$ lsblk -o NAME,MOUNTPOINTS -J | yq '.blockdevices[]  '
{"name": "loop0", "mountpoints": ["/snap/core18/2812"]}

$ lsblk -o NAME,MOUNTPOINTS -J | yq '.blockdevices[] | select(.name == "nvme1n1") | length '
2

$ lsblk -o NAME,MOUNTPOINTS -J | yq '.blockdevices[] | select(.name == "nvme1n1") '
{"name": "nvme1n1", "mountpoints": [null]}

$ lsblk -o NAME,MOUNTPOINTS -J | yq '.blockdevices[]  '
{"name": "loop0", "mountpoints": ["/snap/core18/2812"]}
{"name": "loop1", "mountpoints": ["/snap/core20/2182"]}
{"name": "loop2", "mountpoints": ["/snap/lxd/27037"]}
{"name": "loop3", "mountpoints": ["/snap/amazon-ssm-agent/7628"]}
{"name": "loop4", "mountpoints": ["/snap/lxd/27428"]}
{"name": "loop5", "mountpoints": ["/snap/snapd/20671"]}
{"name": "loop6", "mountpoints": ["/snap/snapd/21184"]}
{"name": "nvme1n1", "mountpoints": [null]}
{"name": "nvme0n1", "mountpoints": [null], "children": [{"name": "nvme0n1p1", "mountpoints": ["/"]}, {"name": "nvme0n1p14", "mountpoints": [null]}, {"name": "nvme0n1p15", "mountpoints": ["/boot/efi"]}]}
