hashboot/README.md

**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.

# Install

* Make hashboot executable
* Place hashboot anywhere in ${PATH}
* Install the appropriate init script
* If applicable, copy kernel-hook to /etc/kernel/post{inst,rm}.d/zzz-hashboot
(make sure it is called after all other hooks)
* To generate the manpage, install [asciidoc](http://asciidoc.org/) and run
`build_manpage.sh`.

# Usage

* First run creates a configuration file. Select the desired checkroutines
* Run `hashboot index` to generate checksums and a backup for /boot and MBR
* Run `hashboot check` to check /boot and MBR
* Run `hashboot recover` to replace corrupted files with the backup

# Notes

* You can't use the openrc/sysv init scripts with parallel boot.
