Well, I certainly believe that the ccd is stable ... It's been in use on 
a production machine at Oregon State U's CS Dept since 1.0 on an hp380, 
their www/ftp/gopher server.  Actually, there are 3 ccds on that machine 
now, one 2-hp7937 and two 4-hp7937.

As for on a non-hp300 platform, I hacked config.new a while back to DTRT 
with ccd configuration stuff, and have a ccd on two Toshiba MK438FB SCSI2 
disks on my i486.  I rely on it everyday -- it has _all_ of my 
work-related source on it.

The ccd as it stands in the tree works only on the hp300 (and probably 
the pmax with very little effort, like the right conf.c entries).  
Really, the correct thing to do with the ccd is dynamic configuration, 
which is what I've been working on for the last couple of weeks (well, I 
was really on vacation last week.. :-)  It's not quite done yet in that 
`it works', but there's alot of things that can be done better (I have a 
27-item list :-)
