I was probably tired yesterday and did not understand properly you
request. So let me summarize with my words and tell me if I better
understand this time: :^)

You want dar to record in the backups the root of the backup (either
explicitely specified with -R or implicitely when no -R option is
provided). At restoration or comparison time, if the user specifies
--in-place option no -R option should be provided and dar will use the
path recorded at backup time for the root backup, which would restore
file in their original path.

Is that correct?

What should be done when merging two backups having recorded two
different root backup? Does not storing any root backup directory would
be OK? In which case --in-place option would lead to an error?

in dar_manager you can store in the database some arguments that will be
passed to dar. Of course you can manually specify a -R option, in that
case at restoration time you don't have to specify the -R path, but
that's different from what I understand from your request :
- different backup may have different -R option in a given database
- the -R provided option may not match the original one
