There had been lots of responses to that.

Yes, the most repeated argument has been mount /usr via NFS.
Unfortunately, nobody yet explained how do they update the resulting
cluster of machines.

I guess there is a way if you want to upgrade your machines one by one : temporarily have 3 instances of /usr. The not-yet-upgraded machines will use /usr(old), the upgraded machines /usr(new), and the machine currently being upgraded will work on a /usr(tmp) which is a copy of /usr(old) and which it will upgrade into a copy of /usr(new).

Now there is another way, which is to upgrade just one machine and clone its hard drive (except for the couple of files which need to be different).

So that's two fairly easy ways to do it. There may be more clever ones.
