|
|
* If trying to unmount the raw device in Linux, we get:
|
|
* > umount: /dev/sdN: not mounted
|
|
* Therefore we use the ?* glob to make sure umount processes
|
|
* the partitions of sdN independently (even if they contain multiple digits)
|
|
* but not the raw device.
|
|
* We also redirect stderr to /dev/null to ignore warnings
|
|
* if a device is already unmounted.
|
|
* Finally, we also wrap the command in a boolean expression
|
|
* that always evaluates to true to ignore the return code,
|
|
* which is non zero when a device was already unmounted.
