== NAME
hashboot - generate checksums and a backup for `/boot` MBR and BIOS.
== SYNOPSIS
*hashboot* _index_|_check_|_recover_
== DESCRIPTION
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 installed, hashboot can
check bios for modifications too.
