efibootmgr can't do anything other than removing entries and changing boot order.

Whenever I try to create an entry, I get this message:

>efibootmgr -v -v -c ...
Could not prepare Boot variable: No such file or directory
error trace:
 util.h:323 get_file(): could not open file "/sys/devices/pci0000:00/firmware_node/uid" for reading: No such file or directory

 efibootmgr.c:287 make_var(): make_linux_load_option() failed: No such file or directory
 efibootmgr.c:336 make_var(): Could not set variable: No such file or directory

Actually, there is no such file as uid in /sys/devices/pci0000:00/firmware_node/, but whose fault is it?

>ls -1 /sys/devices/pci0000:00/firmware_node/

Also, I updated the BIOS to the latest version as in #73 and it had no effect.

Any ideas?

I think this is the same issue as https://github.com/rhboot/efivar/issues/120. Downgrading from sys-libs/efivar-36 to sys-libs/efivar-35 on gentoo seemed to fix it for me.

Errors disappeared, probably after efibootmgr or kernel update.
