Are there any other big projects coming down the line that have indicated a need for rust support? Obviously you don't have to worry about the Linux kernel but I wonder how much rust userspace you currently have packaged? Do you have the rust-vmm vhost-device binaries for example? -- Alex Bennée Virtualisation Tech Lead @ Linaro
