|
Mount a readonly file system from another computer across rednet. The
|
|
target computer must be running OpusOS or redserver. Dissimlar to samba
|
|
in that a snapshot of the target is taken upon mounting - making this
|
|
faster.
|
|
|
|
Useful for mounting a non-changing directory tree.
|

|
|
Syntax:
|
|
rttp://<id>/directory/subdir
|
|
|
|
Examples:
|
|
rttp://12/usr/etc
|
|
rttp://8/usr
