.Pp
|

Delegations are supported under Linux with the exception of
|
||
|
|
.Sy mount ,

|
.Sy unmount ,
|
||
|
|
.Sy mountpoint ,

|
|
.Sy rename ,
|
||
|
|
and
|
||
|
|
.Sy share .
|
||
|
|
These permissions cannot be delegated because the Linux
|
||
|
|
.Xr mount 8
|
||
|
|
command restricts modifications of the global namespace to the root user.
