== NAME

hashboot - allows you to execute files from compiled languages as scripts.

== 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.
