Linux fans wondering why they still don't have a friendly UEFI Secure Boot option for Windows 8 PCs won't get a solution in hand this week, but they'll at least get an explanation. The Linux Foundation's primary backer for the alternative OS efforts, Parallels' server CTO James Bottomley, has revealed that Microsoft's requirements for signed, Secure Boot-ready code are tough if developers aren't entirely onboard its train of thought. The Redmond crew demands a paper contract signature (remember those?), agreements on work beyond the relevant software and a packaging process that complicates attempts to use open-source tools. Bottomley has already overcome most of these challenges, although he's still waiting for a Linux Foundation-specific key that should theoretically clear a major hurdle. Whether or not that leads to a remedy in days or weeks is up to Microsoft; in the meantime, we'll take comfort in knowing that a signature is so far a convenience for booting into Linux, rather than a necessity.
