The initial implementation of this is bootstrapped using a fork of Poky, so we should merge back the upstreamable changes and considering supporting ostree as a deployment method. 44188 1 walters 2014-06-25 19:26:55 +0000 A potential incremental step is to simply take the current RPM/dpkg output, and commit that to the tree directly. This is quite simple to do, but is slow as it incurs the cost of re-SHA256 checksumming all of the input again. What gnome-continuous does is to store components[1] a sub-commits in the same repository, then the final tree(s) are a union. We avoid checksumming again by computing a mapping from (device,inode) to checksum in the repository (as they're all hardlinks). See also https://bugzilla.gnome.org/show_bug.cgi?id=707827 Doing something more like Continuous would involve nontrivial changes to the package layer to optimize things. However, I am looking at some of these optimizations also in the context of rpm-ostree: https://github.com/projectatomic/rpm-ostree 44273 2 walters 2014-07-01 23:09:21 +0000 Also, this would significantly help Continuous because right now it's a poky fork, instead of an OE layer as it should be. 73900 3 clopez 2017-06-08 15:07:48 +0000 What is the status of this? From what I have been reading (didn't tried), this has been already integrated into AGL (an OpenEmbedded-based distro). https://wiki.automotivelinux.org/subsystem/agl-sota/ostree And for Poky, there is a layer providing the missing OSTree integration https://github.com/advancedtelematic/meta-updater Is Poky planning to integrate support for OSTree directly into the core? 75631 4 mark.hatle 2017-08-03 21:43:12 +0000 I'm not the right assignee for this. At present I have no plans to work on OSTree items. 92915 5 ross.burton 2022-04-01 11:14:08 +0000 I don't think ostree belongs in core, and meta-updater covers integration.
