fwupdate - Tools for using the ESRT and UpdateCapsule() to apply firmware updates The actual binary (fwup*.efi) is not automatically installed to your ESP. Copying it from /usr/libexec/fwupdate/ is left to be handled by the package admin. If you do not use the standard directory (/boot/efi/EFI/Slackware), you'll also need to adjust /usr/libexec/fwupdate/cleanup to cleanup the correct directory. I have not actually used this efi binary for anything yet. This package provides the libs needed by fwupd to update firmware, which is what I am using it for. The efi binary is included however for completeness.
