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 installed, hashboot can check the BIOS for modifications too.
Install
Packages
Void Linux
