Essentially, when we generate RootFS today for Ubuntu 14.04/16.04 Armhf, it takes about 17 mins on our official build machines, something that I would like to reduce without impacting correctness of cross-compilation.\r\n\r\nOne approach to this would be for us to create our Docker images with these RootFS already generated. However, it relies on the fact that the generated RootFS changes very infrequently - what are your thoughts on the topic? Does the cross toolset (persisted in RootFS) change very often?\r\n\r\nIf not, I can see us generating a Docker image that contains RootFS for Armhf, armel, x86, etc.\r\n\r\nLet me know what you think.\r\n\r\nCC @janvorli "},"comment":{"url":"https://api.github.com/repos/dotnet/coreclr/issues/comments/287991712","html_url":"https://github.com/dotnet/coreclr/issues/9553#issuecomment-287991712","issue_url":"https://api.github.com/repos/dotnet/coreclr/issues/9553","id":287991712,"user":{"login":"hseok-oh","id":18611688,"avatar_url":"https://avatars1.githubusercontent.com/u/18611688?v=3","gravatar_id":"","url":"https://api.github.com/users/hseok-oh","html_url":"https://github.com/hseok-oh","followers_url":"https://api.github.com/users/hseok-oh/followers","following_url":"https://api.github.com/users/hseok-oh/following{/other_user}","gists_url":"https://api.github.com/users/hseok-oh/gists{/gist_id}","starred_url":"https://api.github.com/users/hseok-oh/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/hseok-oh/subscriptions","organizations_url":"https://api.github.com/users/hseok-oh/orgs","repos_url":"https://api.github.com/users/hseok-oh/repos","events_url":"https://api.github.com/users/hseok-oh/events{/privacy}","received_events_url":"https://api.github.com/users/hseok-oh/received_events","type":"User","site_admin":false},"created_at":"2017-03-21T06:51:47Z","updated_at":"2017-03-21T06:51:47Z","body":"@MichaelSimons To avoid risk that you commented, I prefer option 3: create our own i386 ubuntu image.
