Here is a short runbook for the Bluefin installation process. Read the entirety of this documentation in order to ensure survival. (In case of a raptor attack).

Verifying Downloads with Checksums#

Checksums allow you to verify that your download completed successfully and wasn't corrupted or tampered with. After downloading an ISO, you can compare its checksum to the official checksum file to ensure integrity. While optional, verification is recommended for important installations.

How to verify checksums using sha256sum#

Download both the ISO file and its corresponding CHECKSUM file
- For example: bluefin-stable-x86_64.iso and bluefin-stable-x86_64.iso-CHECKSUM
Generate the checksum of your downloaded ISO:
```
sha256sum bluefin-stable-x86_64.iso
```

Verify using the official checksum file:

sha256sum -c bluefin-stable-x86_64.iso-CHECKSUM

Confirm success: You should see bluefin-stable-x86_64.iso: OK. If verification fails, re-download the ISO.

Example:

# Generate checksum of downloaded file
$ sha256sum bluefin-stable-x86_64.iso
a1b2c3d4e5f6789012345678901234567890abcdef1234567890abcdef123456 bluefin-stable-x86_64.iso

# Verify against official checksum file
$ sha256sum -c bluefin-stable-x86_64.iso-CHECKSUM
bluefin-stable-x86_64.iso: OK
