Is it possible to give an app rights to the file system on a Netware
box to find the msi it needs to install even if there isn't a user
logged in to the workstation?

We have an app associated with workstations and when we tried to push
it a number of installs failed because the users were logging on
workstation only.

This is also relevant to apps which install as "unsecure system user"
because they do not inherit the logged-in user's Netware file system
rights. In the past we've given the [public] trustee rights in order to
get round this problem but would like a better solution.
