| that's how some phone OSes update the system (by having 2 read only fs) that's how Chrome updates itself, but without the symlink part |

| No snapshotting at all? Thinking about it.. The filesystem does not support it I suppose. |

| not surprised about the chrome part, but pretty shocked at the phone OS part. I know APFS migration was done in this way, but wouldn't storage considerations for this be massive? |

| ▲ | slopusila 14 hours ago | parent | next [-] | | what would be more massive would be phones not booting up because of a botched update. this way you can just switch back to the old partition | |
| ▲ | marmarama 14 hours ago | parent | prev [-] | | Not really, because only the OS core is swapped in this way. Apps and data live in their own partitions/subvolumes, which are mutable and shared between OS versions. The OS core is deployed as a single unit and is a few GB in size, pretty small when internal storage is into the hundreds of GB. |
