/**
|
|
|
|
* @page how_mount_works How mount works in barebox
|
|
|
|
|
|
|
|
Mounting a filesystem ontop of a device is working like devices and
|
|
|
|
drivers are finding together.
|
|
|
|
|
|
|
|
The mount command creates a new device with the filesystem name as the
|
|
|
|
driver for this "device". So the framework is able to merge both parts
|
|
|
|
together.
|
|
|
|
|
|
|
|
By the way: With this feature its impossible to accidentely remove
|
|
|
|
partitions in use. A partition is internally also a device. If its
|
|
|
|
mounted it will be marked as busy, so an delpart command fails, until
|
|
|
|
the filesystem has been unmounted.
