--- Comment #1 from xtouqh at icloud.com ---
Looking at the error message and breakdown_name() in usr.sbin/efivar/efivar.c,
this rather looks like "efivar cannot write to EFI variables which have a '-'
in their name".  If you look at the code linked below, the issue is quite
obvious -- we use strrchr() to find the end of GUID, and in this case it's not
correct:

https://svnweb.freebsd.org/base/head/usr.sbin/efivar/efivar.c?revision=366165&view=markup#l87

This needs a better way of distinguishing between GUID and var name.
