I apologize for the tone of my first message. Skip put the words better in his rephrasing. I was speaking only for myself -- I have no part in applying patches to Plan 9 anymore. I submit changes the same as everyone else.
I would hope that any patch changing the behavior of RFNOMNT would be based on someone's experience using the change for a while and exploring the consequences, rather than design on a mailing list. The various RFNOMNT threads seemed to have mostly the former, and then there was talk of a patch. That--talk of submitting patches to change subtle, low-level functionality without having any practical experience with the change--is what I found scary. Russ
