Public bug reported:
I have been experimenting with the kernel's support for booting from
UEFI. Using efibootmgr, I can successfully create new NVRAM variables
and successfully delete existing ones. However, modifying existing
variables does not work.
According to the documentation, I should be able to, for instance, type
the following to change the label:
# efibootmgr -b 0019 -L 'new label for this variable'
But no actual change is made. Thus, to make changes, I have to delete an
existing variable and then recreate it. This is suboptimal because
creating a new variable always places that variable at the front of the
boot order list. Fortunately, the -o switch works, so I can return the
boot order to my preference.
It would be better, though, if the -b switch worked properly.
