On a related note vice-setup seems to take a rather long time when it 
gets to this point:

Proceed, and wipe out old data? [y/n] y

LOG file has been initialized!

Rdsinit will initialize data and log.
This takes a while.
rvm_initialize succeeded.
Going to initialize data file to zero, could take awhile.

...... and then it stops. This process is running at 100% CPU:

/usr/sbin/rdsinit -f /usr/coda/data/log /usr/coda/data/data 4294967296 
0x50000000 4293853184 1048576 80 64

It doesn't appear to be griding onto the disk, and the /usr/coda/data/data 
is 0 bytes.

Would I be correct in guessing this is not what is supposed to happen?
