Examining both the Oneiric 11.10 and Precise 12.04 kernel configs, CONFIG_EFI_VARS is built into the kernel for each of those releases: config.common.ubuntu:1536:CONFIG_EFI_VARS=y This was built in due to Bug 837332 as debian-installer relies on having access to efivars when installing in EFI mode. ** Changed in: linux (Ubuntu) Status: Confirmed = Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/935736 Title: /sys/firmware/efi/vars unavailable (efivars module not loaded) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/935736/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
