Hi guys, With systemd-193 and linux-3.6 we will finally have reliable support for btrfs multi-device filesystems (assembling them used to be racy). However, the added udev rules that makes this work do not work at all on pre-3.6 kernels. We could keep the old (racey) rules in the btrfs package to deal with this situation. However, that means scanning all btrfs devices twice on boot for everyone on post-3.6 kernels. As I expect the number of people using multi-device btrfs (which is still experimental) with an linux-lts kernel to be limited, I'm not too keen on optimizing for this case. I propose we either just drop the old btrfs rules and tell users of linux-lts+btrfs multi-device to upgrade to linux, or we add the rules to the linux-lts package. Any thoughts? Cheers, Tom
