            Bug ID: 248545
           Summary: zfs: add possibility to create an initial send stream
                    without intervening snapshots
           Product: Base System
           Version: 12.1-RELEASE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: bin
          Assignee: bugs at FreeBSD.org
          Reporter: d8zNeCFG at aon.at

Scenario:
- FreeBSD 12.1-RELEASE-p6
- Using "zfs send" to create backups
- Using "-R" flag to create backups of zfs filesystem hierarchies
- Using "-I" or "-i" to create incremental backups
- For these backups, specifically named snapshots are used which are created
using "zfs snapshot -r <top filesystem>" (the <top filesystem> is not
necessarily a complete pool but can be a subset of a pool).
- There are other (intervening) snapshots that are irrelevant for backup
purposes.

Result:
1. It is possible to create a full recursive backup stream (similar to a level
0 dump) using "zfs send -R ...", including all intervening snapshots, even
those irrelevant for backup purposes.
2. It is NOT possible to create a full recursive backup stream using "zfs send
-R ...", excluding all intervening snapshots.
3. It is possible to create an incremental recursive backup stream using "zfs
send -R -I ...", including all intervening snapshots.
4. It is possible to create an incremental recursive backup stream using "zfs
send -R -i ...", excluding all intervening snapshots.

Expected result:
It should be possible to create a full recursive backup stream WITHOUT the
intervening snapshots (case 2. above).
