- I don't know of any way to "regress" from diskfull to remote /usr. However,
- doing the installation of the client and choosing "install for use with remote
- /usr" will not require you to go through the 3.2.2 update process. If you
- have installed 3.2.2 on the server which will be serving the remote /usr,
- those updates will be shared by the client. The only thing that you will lose
- is any customization which you may have performed in the clients' miniroots.

-
- There is a minimal /usr on the client which will come up if it cannot contact
- the server. There is not much there. Just enough to get the thing booted
- and allow you to "vi" a few things.

- I am not sure about this. I think it is probably a manual process. If the
- server updates its /usr, the client must run the installp command which will
- install the root portions of the PTFs onto the clients miniroot. I think the
- syntax is
- installp -acg -Or all
-
- But don't hold me to it.
