Generally speaking, yes -- but, the wrapper program which does
the vos releases does check for a `not now' sentinal file.
By regular intervals, I mean 6pm, midnite, 6am, so it's
not really intruding on the (normal) workday.

We use the following scheme:
/usr -> /afs/iastate.edu/system/ro/dec/v5/usr
| | |
ro or rw mntpt | our "version"
arch
where we generally have 3 versions "live" at a time,
the "mature", the "current", the "advanced" -- people
who point their machine at advanced get new goodies
sooner at the cost of things not always being exactly
the same as they were yesterday. (Although with the
cost of disks having dropped 20-fold in the 5 years
we've been doing this, we're relying less and less
on a networked /usr tree.)
