Re: deprecating /usr as a standalone filesystem?

It's not particularly difficult.  You update the system master and push
that update into NFS, synchronizing any non-/usr data as you need to
across all the systems mounting that NFS partition.  If you don't want
to take downtime, you have two chroots on the NFS server and pivot
systems back and forth between the two chroots as you do updates.

People did and still do this all the time with AFS.  It's pretty
well-established how to make it work.

I personally don't care any more because hard drives have gotten a lot
bigger, but it's technically quite feasible.

Certainly looks tenable right now to me.
