One thing that we totally lose the ability to do is use the capsule interface for things *other* than firmware updates, e.g.
https://lkml.org/lkml/2013/10/16/327
Also, requiring embedded or custom OS to include fwupdate into their existing boot solutions is a bit heavy handed when literally all they want to do is cat a binary blob to a sysfs file.
I don't see why we can't have both solutions.
Another thing is that ESRT isn't going to be supported by every platform.
So, for the sysfs interface, let's not allow loading from /lib. Let's not require a userland tool. Let's just do,
# echo /path/to/my/awesome/capsule.bin > /sys/../capsule
and be done with it.
Hmmm?
