| 41 | The
|

| 42 | vfs_worm
|

| 43 | module controls the writability of files and folders depending on their change time and a adjustable grace period\&.
|
|---|
| 44 | .PP
|
|---|
| 45 | If the change time of a file or directory is older than the specified grace period, the write access will be denied, independent of further access controls (e\&.g\&. by the filesystem)\&.
|
|---|
| 46 | .PP
|
|---|
| 47 | In the case that the grace period is not exceed, the worm module will not impact any access controls\&.
