SEC.01

The playbook

The run starts read-only: the recon probes decide what happens next. The steps that follow are adapted to the distribution and state found — a real machine is rarely clean.

  1. 01recondoes the device exist? partitions, FS, mount
  2. 02reconsignature present (FS, LVM, RAID, partition table) = data → NEVER format
  3. 03reconsystem disk: the device must not be part of it
  4. 04recondevice member of an LVM, mdadm RAID or ZFS pool? → stop
  5. 05reconexisting fstab entry for this device or mount point?
  6. 06reconmount point already in use or not empty (its content would be hidden)?
  7. 07reconFS tools present (e2fsprogs, xfsprogs, btrfs-progs)?
  8. 08actInstall the FS tools (if missing)verify
  9. 09actFormat ${device} (only if no signature)destructiveverify
  10. 10actCreate the mount pointverify
  11. 11actAdd to fstab (UUID, nofail)destructiveverify

What it verifies

Each step ships its own check. The run only moves on when the check passes, so what the recipe reports as done is what is actually on the server.

  1. 01Install the FS tools (if missing)Verified bycommand -v mkfs.${fs}
  2. 02Format ${device} (only if no signature)Verified byblkid -s TYPE -o value ${device}
  3. 03Create the mount pointVerified bytest -d ${mountpoint} && echo ok
  4. 04Add to fstab (UUID, nofail)Verified bygrep -c "^UUID=$(blkid -s UUID -o value ${device}) " /etc/fstab
  5. 05MountVerified byfindmnt -n -o SOURCE,FSTYPE ${mountpoint}

SEC.03

Guardrails

Non-negotiable instructions the run must respect, whatever it finds on the server.

REFUSE to format a device carrying a signature (FS, LVM, RAID, partitions), mounted, or part of the system disk — ask for explicit confirmation, otherwise stop. Never a force option (-f/-F). UUID in fstab, never the device name, always nofail. Back up /etc/fstab first.

How a recipe runs in Servor

Servor is zero-knowledge: the platform cannot execute anything on its own. When you launch this recipe, a run reads the reconnaissance, plans the steps and asks for your approval. Each approved command is signed by your browser — with a key the server never sees — then relayed verbatim to the agent, which verifies the signature locally before executing.

  • 01Read-only reconnaissance before any change
  • 02Every command signed by your browser, approved by you
  • 03Each step verified before the run moves on, every run kept in the history
