Hi,
I have written a technical report of my UEFI research, early test
results and conclusions:
https://tails.boum.org/blueprint/UEFI/
Wrapping up the usable test results I've received so far:
* No regression was reported: the ISO images with UEFI support boot
at least as well as our non-UEFI ones.
* 4 different MacBooks (with rEFInd installed) and 3 ThinkPads, that
are unable to boot a non-UEFI device installed with Tails
Installer, successfully boot off a UEFI device installed the
same way.
* A few laptop PCs that support UEFI now boot Tails just fine in
UEFI mode, while one had to switch to Legacy BIOS mode previously.
Next steps:
1. Ship a 64-bit kernel (#5456) in 0.23. I'm committed to lead this
to a conclusion. Assigned to the 0.23's RM (anonym) for review.
2. Write documentation for UEFI boot (#6562). I have listed on the
ticket what (I already know) must be done in this area.
That's a non-trivial task, and I am not sure we want to tackle it
(UEFI support is a goal for 2.0) now. But if we can come up with
a small subset of these tasks that would be good enough to add
*beta* UEFI support to 0.23, then I'd be very happy. sajolida, it
would be great if you could have a quick look to evaluate this.
3. Workaround the syslinux menu display bugs (#6576) I have seen on
various hardware. Some of these bugs (on Mac) are blocking boot
entirely, some are merely inconveniences.
Cheers,
