This is the amount of time, in seconds, to wait for the block device |
|

the root filesystem is on to become available, after the kernel that |
|

modules for the rootfs and device are loaded. |

|

Scripts used to mount and check block devices (filesystems and swap), as well
|
|
||||||
as hotplug scripts to automount and check block devices when hotplug event (e.g.
|
|
||||||
from plugging in a device) occurs.
|
|
||||||
Also includes preinit scripts for mounting a block device as the root filesystem.
|
|
||||||
This allows one to have the root filesystem on devices other than the built in flash
|
|
||||||
device.
