Entry point for wrolpi-mounts.service.
|
||
|
|
|
||
|
|
This module is intentionally tiny: it wires up production dependencies
|
||
|
|
(real subprocess executor, real wrolpi uid/gid lookup, real fstab.yaml on
|
||
|
|
the drive) and asks the Reconciler to apply. All real work lives in
|
||
|
|
controller.lib.reconciler; tests for the orchestration live in
|
||
|
|
test_reconciler.py using FakeMountExecutor.
