Currently Heads will check files in /boot for tampering before booting
into a system. It would be nice if you could use the trusted environment
within Heads and extend this to check files in / itself. This new script
adds that functionality, however due to the length of time it takes to
perform these kinds of checks, it doesn't run automatically (yet).
This feature can be configured from the config GUI - the root device/
directories to check can be set, and it can be configured to run during
boot.
To make this a bit easier to use, I added a feature to detect whether
the hash file exists and if not, to display a more limited menu to the
user guiding them to create the initial hash file. Otherwise it will
display the date the file was last modified, which can be useful to
determine how stale it is.
Unify the CONFIG_BOOT_KERNEL_ADD/REOVE parameters for all
Librem boards. Ensure IOMMU disabled for the GPU, and that
duplicated IOMMU params are not passed to the kernel.
