A convenience wrapper around ostree_repo_get_min_free_space_bytes().
Clients programs like gnome-software can get the value of minimum free
space as defined in the OSTree repo. This can be useful in various
disk-space checks these client program can implement.
At Endless, we have downstream heuristics in gnome-software which
determine the success/failure likelihood of an install/update
operation to some extend. Depending upon the likelihood of the
success/failure we dispatch install/update/auto-update operations.
With client programs gaining features such as auto-updates, it makes
sense to have a min-free-space API so that these programs can check
free-space availablity vs minimum free space defined by user inside
OSTree's repo before auto-updating. Although, OSTree will certainly
fail operations over-stepping min-free-space's value; It's just a
matter of convenience to provide a way to query the value to client
programs as well.
