<title>Reproduce and Verify Filesystems [2016 ContainerCon EU]</title>
<meta name="description" content="A side effect of the many new ways to package filesystems (here&#39;s looking at you, containers!), is that filesystems are being copied around without many of the features that traditional packaging provided (i.e. `rpm -qV ...`). Much progress has been made for reproducible checksums, of which Docker now includes for better content addressibility. In this talk Vincent Batts will review options for distributing filesystems with reproducibility, and verifying the at-rest outcomes.">

In this talk Vincent Batts will review options for distributing filesystems with reproducibility, and verifying the at-rest outcomes.","width":960,"height":700,"visibility":"self","published_at":null,"sanitize_messages":null,"thumbnail_url":"https://s3.amazonaws.com/media-p.slid.es/thumbnails/419084c9510c580808fc95f79d4c7a95/thumb.jpg","view_count":225,"user":{"id":352550,"username":"vbatts","name":"Vincent Batts","description":"","thumbnail_url":"https://www.gravatar.com/avatar/a76bbb02d3ce311820f53ef484c0f8bf?s=140\u0026d=https%3A%2F%2Fstatic.slid.es%2Fimages%2Fdefault-profile-picture.png","paid":true,"pro":true,"lite":false,"team_id":32,"settings":{"id":185974,"present_controls":true,"present_upsizing":true,"present_pointer":false,"present_notes":true,"default_deck_tag_id":null},"enterprise":true,"membership":{"role":"member","manager":false,"activated":true}},"background_transition":"none","transition":"none","theme_id":176,"theme_font":"overpass2","theme_color":"no-color","auto_slide_interval":0,"comments_enabled":true,"forking_enabled":false,"rolling_links":false,"center":false,"shuffle":null,"should_loop":false,"share_notes":false,"slide_number":false,"slide_count":22,"rtl":false,"version":2,"collaborative":false,"deck_user_editor_limit":1,"data_updated_at":1474548805830,"font_typekit":null,"font_google":null,"notes":{"8ed56a11a24a87544db45844eb49f2ff":"demo","0c55eeb9a60659b64c85ed2af6b7de8d":"demo","b03d420eef149b7a255b09452e70846c":"demo","0a9edb24c627567228da4a3955f93338":"demo","504b417f0e0fcada82f82c7f48fc8a05":"demo ./go-mtree.sh","6d5f286ddb5ec2821099d0319b33e9f1":"demo ./mtree.sh","8526a808386bdf837654854c12116ea7":"no demo for this, they can do that on their own"}}};
