**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.
|
||||
|
||||
We moved our code to
|
||||
[schlomp.space](https://schlomp.space/tastytea/hashboot) but we keep the
|
||||
[GitHub-repo](https://github.com/tastytea/hashboot) as a mirror.

# Install
|
||||
|
||||
## Packages
|
||||
|
||||
### Void Linux
|
||||
|
||||
``` shell
|
||||
xbps-install -S hashboot
|
||||
```
|
||||
|
||||
### Gentoo Linux
|
||||
|
||||
Ebuilds are available via the
|
||||
[tastytea repository](https://schlomp.space/tastytea/overlay).
|
||||
|
||||
``` shell
|
||||
emerge -a sys-apps/hashboot
|
||||
rc-update add hashboot boot
|
||||
```
|
||||
|
||||
### Arch Linux
|
||||
|
||||
Use the [package from AUR](https://aur.archlinux.org/packages/hashboot/).
|
||||
|
||||
## Manual
|
||||
|
||||
### Any distro
|
||||
|
||||
The releases on
|
||||
[schlomp.space](https://schlomp.space/tastytea/hashboot/releases) are
|
||||
PGP-signed. The key-ID is `F7301ADFC9ED262448C42B64242E5AC4DA587BF9`
|
||||
(`242E5AC4DA587BF9`). You can fetch it with `gpg --locate-key
|
||||
autosign@tastytea.de`.
|
||||
|
||||
* Make hashboot executable
|
||||
* Place hashboot anywhere in ${PATH}
|
||||
* Place hashboot anywhere in $PATH
|
||||
* Install the appropriate init script
|
||||
* If applicable, copy `hooks/kernel-postinst` 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`.
|
||||
* If applicable, copy kernel-hook to /etc/kernel/post{inst,rm}.d/zzz-hashboot (make sure it is called after all other hooks)
|
||||
|
||||
# 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
|
||||
* 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.
|
||||
* The systemd and SysVinit init scripts have not been tested in a while, but
|
||||
will probably work.

|

== 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.
