[Bug 1265990] Re: efivarfs shouldn't block boot

[Steve Langasek]

The efivarfs is a kernel fs which is provided by the kernel in all
situations where it applies, and failures to mount it should not be
silently ignored on boot because it provides critical functionality
which could cause significant problems with the system post-boot
(including failures to install/update bootloaders or apply security
updates to firmware).  So I am closing this bug as invalid.

If you have an EFI system where efivarfs is not available, that is
almost certainly a bug in the kernel you're running.  It's not clear
from your message if you are using an official Ubuntu kernel, so I have
not reassigned this bug.  However, if this is happening with an official
Ubuntu kernel, please reopen and reassign the bug to the 'linux'
package.
