unionfs and tmpfs?

[Ivan Voras]

Hi

I'm having trouble mounting tmpfs with unionfs above a read-only file
system (cd9660). In my case, /tmp is a tmpfs and I'm doing:

# mount_unionfs /tmp /etc
mount_unionfs: /etc : Operation not supported.

It works if, for example, /tmp is a UFS mounted on a memory device.

Is this intentional?
