Hi,
I found the statement above in the list archive.
I'm currently looking into using mounted storages for an ISP-solution.
Each client would have their own mounted storage as there virtual root.

What is the problem with undo and mounted storages?

Are there other known problems with ExternalMount (and mounted FileStorage)?

Could there be a problem mounting many FileStorage in one base instance?
