**hashboot** hashes all files in `/boot` and the MBR to check them during early
|
|
boot. It is intended for when you have encrypted the root partition but not the
|
|
boot partition. The checksums and a backup of the contents of `/boot` are stored
|
|
in `/var/lib/hashboot` by default. If a checksum doesn't match, you have the
|
|
option to restore the file from backup.
|
|
|
|
If there is a core- or libreboot BIOS and [flashrom](https://flashrom.org/)
|
|
installed, **hashboot** can check the BIOS for modifications too.
