PureBoot Basic mode provides the full Linux userspace in firmware from
Heads without requiring verified boot or a Librem Key.  Basic and
verified boot can be switched freely without changing firmware, such as
if a Librem Key is lost.

PureBoot Basic can apply firmware updates from a USB flash drive, and
having a complete Linux userspace enables more sophisticated recovery
options.
