- Updated `already_formatted()` to use `blkid` plus safe read-only mount for accurate filesystem detection.
- Added conditional `-f` flag to `mkfs` only when `overwrite: true` is set.
- Removed `continue` statements from the shell script to prevent runtime errors.
- Updated Go overlay snapshot tests to reflect new template rendering.
- Ensures disks with leftover signatures but no valid filesystem are properly reformatted during node provisioning.
- sfdisk - partitions the disk
- mkfs - formats partitions
- mkswap - formats partitions for swap
- systemd.mount - explicit creation of systemd mount units
- systemd.swap - explicit creation of systemd swap units
