[developers] running LOGON from an NFS partition

[Rebecca Dridan]

I have run LOGON from an NFS partition. See 
http://lists.emmtee.net/archive/logon/2009/000126.html. I assumed my 
problem was caused by the partition being mounted read-only, but perhaps 
I would have run into issues anyway. At any rate, the work-around I list 
there lets me run LKB, load a grammar and parse from the (read-only) NFS 
partition, and no one replied with any warnings :)
