No, it is very old. I believe that is there to accommodate installations
with MR-AFS. MR-AFS is for using AFS with HSM systems but is not freely
available or open source or anything; you can google around for what
little information exists about it. I'm not sure if it's still in use.
Those rpcs hard code the commands they run, ugh...
I don't have any familiarity with it, but from what I've seen in the
OpenAFS source, I think the 'scanner' process is something that shuffled
data between disk and tape. Normally it runs continuously or something,
but those commands allow you to temporarily disable or enable
