disc labels on 4.3 (vax)

[Andrew Weeks]

We have recently received a new 4.3 Vax release from MtXinu, which
contains a disk-labelling system (probably that from 4.3-tahoe).

The question I want to ask is, will writing a label onto the disc affect
the file system? i.e.  can I label a `live' disc, or should I only label
a blank disc which I am then going to restore onto? 

The documentation we have doesn't say anything about this, which
probably means it's safe, but then the label must take up some space,
where can it get it except at the expense of files?
