>Environment:
>Description:
As of NetBSD 10 we have a /dev/efi interface, but no tools to operate on it, e.g. to query or set EFI variables or configure the EFI boot manager.
>How-To-Repeat:

>Fix:
FreeBSD as of 11.1 has efivar(8), efidp(8), and efibootmgr(8):

https://man.freebsd.org/cgi/man.cgi?query=efivar&manpath=FreeBSD+14.0-RELEASE+and+Ports
https://man.freebsd.org/cgi/man.cgi?query=efidp&manpath=FreeBSD+14.0-RELEASE+and+Ports
https://man.freebsd.org/cgi/man.cgi?query=efibootmgr&manpath=FreeBSD+14.0-RELEASE+and+Ports

We can probably just import those.
