maintenance.auto::
	This boolean config option controls whether some commands run
	`git maintenance run --auto` after doing their normal work. Defaults
	to true.

maintenance.autoDetach::
	Many Git commands trigger automatic maintenance after they have
	written data into the repository. This boolean config option
	controls whether this automatic maintenance shall happen in the
	foreground or whether the maintenance process shall detach and
	continue to run in the background.
+
If unset, the value of `gc.autoDetach` is used as a fallback. Defaults
to true if both are unset, meaning that the maintenance process will
detach.

maintenance.strategy::
	This string config option provides a way to specify one of a few
	recommended strategies for repository maintenance. This affects
	which tasks are run during `git maintenance run`, provided no
	`--task=<task>` arguments are provided. This setting impacts manual
	maintenance, auto-maintenance as well as scheduled maintenance. The
	tasks that run may be different depending on the maintenance type.
+
The maintenance strategy can be further tweaked by setting
`maintenance.<task>.enabled` and `maintenance.<task>.schedule`. If set, these
values are used instead of the defaults provided by `maintenance.strategy`.
+
The possible strategies are:
+
* `none`: This strategy implies no tasks are run at all. This is the default
  strategy for scheduled maintenance.
* `gc`: This strategy runs the `gc` task.
* `geometric`: This strategy performs geometric repacking of packfiles and
  keeps auxiliary data structures up-to-date. The strategy expires data in the
  reflog and removes worktrees that cannot be located anymore. When the
  geometric repacking strategy would decide to do an all-into-one repack, then
  the strategy generates a cruft pack for all unreachable objects. Objects that
  are already part of a cruft pack will be expired.
+
This repacking strategy is a full replacement for the `gc` strategy and is
recommended for large repositories. This is the default strategy for manual
maintenance.
+
* `incremental`: This setting optimizes for performing small maintenance
  activities that do not delete any data. This does not schedule the `gc`
  task, but runs the `prefetch` and `commit-graph` tasks hourly, the
  `loose-objects` and `incremental-repack` tasks daily, and the `pack-refs`
  task weekly. Manual repository maintenance uses the `gc` task.

maintenance.<task>.enabled::
	This boolean config option controls whether the maintenance task
	with name `<task>` is run when no `--task` option is specified to
	`git maintenance run`. These config values are ignored if a
	`--task` option exists. By default, only `maintenance.gc.enabled`
	is true.

maintenance.<task>.schedule::
	This config option controls whether or not the given `<task>` runs
	during a `git maintenance run --schedule=<frequency>` command. The
	value must be one of "hourly", "daily", or "weekly".

maintenance.commit-graph.auto::
	This integer config option controls how often the `commit-graph` task
	should be run as part of `git maintenance run --auto`. If zero, then
	the `commit-graph` task will not run with the `--auto` option. A
	negative value will force the task to run every time. Otherwise, a
	positive value implies the command should run when the number of
	reachable commits that are not in the commit-graph file is at least
	the value of `maintenance.commit-graph.auto`. The default value is
	100.

maintenance.loose-objects.auto::
	This integer config option controls how often the `loose-objects` task
	should be run as part of `git maintenance run --auto`. If zero, then
	the `loose-objects` task will not run with the `--auto` option. A
	negative value will force the task to run every time. Otherwise, a
	positive value implies the command should run when the number of
	loose objects is at least the value of `maintenance.loose-objects.auto`.
	The default value is 100.

maintenance.loose-objects.batchSize::
	This integer config option controls the maximum number of loose objects
	written into a packfile during the `loose-objects` task. The default is
	fifty thousand. Use value `0` to indicate no limit.

maintenance.incremental-repack.auto::
	This integer config option controls how often the `incremental-repack`
	task should be run as part of `git maintenance run --auto`. If zero,
	then the `incremental-repack` task will not run with the `--auto`
	option. A negative value will force the task to run every time.
	Otherwise, a positive value implies the command should run when the
	number of pack-files not in the multi-pack-index is at least the value
	of `maintenance.incremental-repack.auto`. The default value is 10.

maintenance.geometric-repack.auto::
	This integer config option controls how often the `geometric-repack`
	task should be run as part of `git maintenance run --auto`. If zero,
	then the `geometric-repack` task will not run with the `--auto`
	option. A negative value will force the task to run every time.
	Otherwise, a positive value implies the command should run either when
	there are packfiles that need to be merged together to retain the
	geometric progression, or when there are at least this many loose
	objects that would be written into a new packfile. The default value is
	6700.

maintenance.geometric-repack.splitFactor::
	This integer config option controls the factor used for the geometric
	sequence. See the `--geometric=` option in linkgit:git-repack[1] for
	more details. Defaults to `2`.

maintenance.reflog-expire.auto::
	This integer config option controls how often the `reflog-expire` task
	should be run as part of `git maintenance run --auto`. If zero, then
	the `reflog-expire` task will not run with the `--auto` option. A
	negative value will force the task to run every time. Otherwise, a
	positive value implies the command should run when the number of
	expired reflog entries in the "HEAD" reflog is at least the value of
	`maintenance.loose-objects.auto`. The default value is 100.

maintenance.rerere-gc.auto::
	This integer config option controls how often the `rerere-gc` task
	should be run as part of `git maintenance run --auto`. If zero, then
	the `rerere-gc` task will not run with the `--auto` option. A negative
	value will force the task to run every time. Otherwise, a positive
	value implies the command should run when the estimated number of stale
	entries that would be pruned is greater than or equal to the configured
	value. The default value is 512.

maintenance.worktree-prune.auto::
	This integer config option controls how often the `worktree-prune` task
	should be run as part of `git maintenance run --auto`. If zero, then
	the `worktree-prune` task will not run with the `--auto` option. A
	negative value will force the task to run every time. Otherwise, a
	positive value implies the command should run when the number of
	prunable worktrees exceeds the value. The default value is 1.
