|
|
|
== 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
|
2019-02-24 15:29:11 +01:00
|
|
|
check bios for modifications too.
