shr – global mountpoints|
bind '#σ' /shr |
The shr device provides global mountpoints in the form of share
directories where 9P services can be mounted.|
Effectively, it is a global mountpoint registry that is separate from private namespaces.
The shr device exports a mount tree and a control tree. The directories in the mount tree #σ are the share mountpoints themselves, while the directories in #σc contain the service files of the share.
To create a new share, create the directory #σc/myshare
The service file can be reopened and passed to mount (see bind(2)) or added to another share.
Multiple services can be mounted under a share forming a union directory. New services get mounted before old ones. Removing the service file unmounts the service from the share.
Creating shares and mounts requires read–write access in the share
directory. The special user none is prohibited from these operations.
