From: Jacek Kryszyn Date: Wed, 28 Aug 2024 19:37:00 +0000 (+0200) Subject: Handle virtual a/b X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=refs%2Fheads%2Fsandbox%2Fjkryszyn%2Fvirtual-ab;p=platform%2Fcore%2Fsystem%2Fupgrade.git Handle virtual a/b This commit adds support for virtual a/b. It is assumed that super contains only one set of partitions instead of two slots. A dm-snapshot is created during upgrade which will be treated as a next partition and change will be applied to it. After booting to fota and successful rw update the snapshot will be merged to an origin partition.
