Hello folks,

Thanks kindly -- and my apologies for picking this up after a while;
fell sick here...

A few questions:

-- If I have multiple drives, do I modify the script to have multiple
efi2, efi3, ..., efiX ?

-- it seems that the script above privileges /boot/efi over /boot/efi2
-- in this case, if /boot/efi becomes corrupted, won't this just copy
the errors to /boot/efi2 and thus destroy it as well, on the next run?

Cheers!
