Read-only snapshots? That'd do it, and of course you can toggle the read- only property (see btrfs property and its btrfs-property manpage). Alternatively, mount the toplevel subvol read-only or noatime on one mountpoint, and bind-mount it read-write or whatever other appropriate *atime elsewhere (or the reverse, if more appropriate). Then use the noatime or read-only one unless you specifically wanted atimes updated. -- Duncan - List replies preferred. No HTML msgs.
