Proper way to specify `SupportedMountOptions`

[Qiyuan Liang]

Hello,

What is the proper way to specify `SupportedMountOptions` with a mount? Tried to specify it with something like this:

{
  destination: mount.destination,
  source: mount.source,
  options: ["ro", "rbind", "dcache=0"],
  type: "bind",
}

and this:

{
  destination: mount.destination,
  source: mount.source,
  options: ["ro", "rbind"],
  dcache: 0,
  type: "bind",
}

But both are not working as expected. It would be great if you could provide an example. Thank you!

Best regards,
Qiyuan

I will respond on https://github.com/google/gvisor/issues/10316. It is an issue in gVisor.

The first way is the right way to do it (append it to options= array).
