Subject: [PATCH 22/22] CLI/new: use configuration variable for backup directory
Date: Sun,  7 Mar 2021 13:27:34 -0400	[thread overview]
Message-ID: <20210307172734.1091264-23-david@tethera.net> (raw)
In-Reply-To: <20210307172734.1091264-1-david@tethera.net>

The stat is essentially replaced by the mkdir for error detection
purposes.  This changes the default location for backups to make
things tidier, even in non-split configurations. Hopefully there is
not too many user scripts relying on the previous location.
