Why Btrfs has some goodness (snapshots, switching between different rw snapshot) which plays particularly well with certain "subvolume layouts". What This MR seeks to implement such a layout, namely a flat btrfs layout, where the top level subvolume (i.e. the btrfs filesystem/partition itself) remains unmounted in all situations, except when making changes to direct child subvolumes of the filesystem. - rename all subvols to follow the common @* btrfs subvol naming scheme. - add subvol @root, because roots home directory shouldn't be rolled back. - make subvol @var not Copy-on-Write (nodatacow) to avoid write - multiplication on logs, VMs, databases, containers and flatpaks. - add subvol @snapshots because that lets us change the root subvol to a read-write snapshot of @ without affecting snapshots. - add subvol @srv because it contains data for Web and FTP servers, which shouldn't roll back together with root subvol. - add subvol @tmp because we don't want to snapshot temporary files. This subvol remains unmounted on the device, unless conditions as laid out in pmaports!4737 are met. - add check and error for btrfs when using rsync installation. |
