Re: EDM's -ro option and running arbitrary scripts w/ in our case caputs

[John William Sinclair <sinclairjw@ornl.gov>]

Carl,

You would think of this in the same manner as you think of someone writing a
script to recursively delete all files in the production directories. In 
other words, as soon as
you allow scripts, you need to implement the -ro controls.

Of course, you can always use EPICS access control.
