# Linux Runtime
|

## File descriptors
|
||
|
|
By default, only the `stdin`, `stdout` and `stderr` file descriptors are kept open for the application by the runtime.
|
||
|
|
|
||
|
|
The runtime may pass additional file descriptors to the application to support features such as [socket activation](http://0pointer.de/blog/projects/socket-activated-containers.html).
|
||
|
|
|
||
|
|
Some of the file descriptors may be redirected to `/dev/null` even though they are open.
