I'm having difficulty finding detailed information about the barman system user in the documentation.
Is there anything special about it? Is it required for use?
I'm asking because the files written by the barman system user inherit the UID and GID of the user, somewhat obviously. I however need the files to be written with the UID of a different user due to how our shared storage pool works. So I would like to use a different system user that has the appropriate UID/GID, or if there is a more appropriate solution that achieves the same thing I'm open to that as well.
Thanks.
