Well, thats what i would expect too. It seems strange that you can't edit or remove singular files from snapshots though you can rmdir acomplete snapshot 'directory' at once. Is this by design? I call it a bug. ;) > /bin/rmdir on the other hand did do a rmdir(2), and that does destroy > the snapshot. It seems to me that the 'base directory' or 'mountpoint' of the snapshot, e.g. .zfs/snapshot/<name> is not immutable, as all files and directories inside the snapshot are: r...@host:/backup/host/.zfs/snapshot/2009-10-14# rmdir bin rmdir: bin: Read-only file system > Although I see sometimes the rmdir fails.

I haven't noticed such behaviour myself. I guess i'm gonna switch off snapdir visibility while rsync runs, or something.
