== 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.
== OPTIONS
*index*::
generate checksums and a backup for `/boot`, MBR and BIOS.
*check*::
check `/boot`, MBR and BIOS.
*recover*::
replace corrupted files with the backup.
== CONFIGURATION
The configuration file is in `/etc/hashboot.conf`.
=== Possible options
[frame="none",grid="none"]
|============
|SAVEDIR | The checksums and the backup are stored here.
|CKMODES | 001=mbr, 010=files, 100=bios.
|MBR_DEVICE | Device with the MBR on it.
|PROGRAMMER | Use this programmer instead of "internal". Will be passed to flashrom.
